For this problem, we are dealing with shear stress and shear strain in a tubular cross-section shaft. When an axial torque is applied to the shaft, it experiences shear stress, which is the force per unit area that is parallel to the cross-sectional area.
a) The maximum shear stress in the shaft can be determined using the formula: τmax = (Tdo)/(2J), where τmax is the maximum shear stress, T is the applied torque, do is the outer diameter of the shaft, and J is the polar moment of inertia, which is given by : J = (π/2)(do^4 - di^4).
The maximum shear stress exists at the outer diameter of the shaft.
b) A sketch of the shear stress on the cross section of the tube would show a circular distribution of shear stress, with the maximum value occurring at the outer diameter.
c) The maximum shear strain in the shaft can be determined using the formula: γmax = τmax/G, where γmax is the maximum shear strain, and G is the shear modulus of the material.
The maximum shear strain exists at the outer diameter of the shaft, where the maximum shear stress occurs.

The resonance frequency for an RLC series circuit can be calculated using the formula
In an RLC series circuit, there are three components: a resistor (R), an inductor (L), and a capacitor (C) connected in series. The resonance frequency is the frequency at which the inductive and capacitive reactances cancel each other out, resulting in a minimum impedance across the circuit.
We are given that the resistor has a value of 310 ohms, but we need to determine the values of L and C.
C = 1 / (4π²f²L)
L = 1 / (4π²f²C)
C = 1 μF = 1 × 10⁻⁶ F
R = 310 Ω
L = 1 / (4π²f²C)
L = 1 / (4π² × f² × 1 × 10⁻⁶)
L = 1 / (1.2566 × 10⁻¹¹ × f²)

an amplifier is formed by cascading 2 amplifiers with the following transfers functions. what is the low-frequency gain, gain at the cut-off frequency and the value of the cut-off frequency?
The gain at the cut-off frequency would be fc = sqrt(fc1 x fc2) and the value of the cut-off frequency would be A(fc) = A1(fc) x A2(fc).
To determine the low-frequency gain, gain at the cut-off frequency, and the value of the cut-off frequency for an amplifier formed by cascading 2 amplifiers with given transfer functions, we need to multiply the transfer functions and analyze the resulting function.
Let's assume the first amplifier has a transfer function of A1(s) and the second amplifier has a transfer function of A2(s). Then the overall transfer function of the cascaded amplifiers would be:
A(s) = A1(s) x A2(s)
To find the low-frequency gain, we need to evaluate the transfer function at a very low frequency (s = 0). At low frequencies, capacitors act like open circuits, and inductors act like short circuits. Therefore, we can simplify the transfer function by replacing all capacitors with open circuits and all inductors with short circuits. Then, we can evaluate the resulting expression at s = 0.
The low-frequency gain would be the value of the transfer function at s = 0, which can be found by:
A(0) = A1(0) x A2(0)
To find the gain at the cut-off frequency, we need to determine the frequency at which the transfer function starts to roll off. This frequency is called the cut-off frequency and can be found by setting the magnitude of the transfer function to 1/sqrt(2) and solving for s.
|A(s)| = 1/sqrt(2)
|A1(s) x A2(s)| = 1/sqrt(2)
|A1(s)| x |A2(s)| = 1/sqrt(2)
Let's assume that the first amplifier has a cut-off frequency of fc1 and the second amplifier has a cut-off frequency of fc2. Then the overall cut-off frequency would be:
fc = sqrt(fc1 x fc2)
Finally, to find the value of the cut-off frequency, we need to substitute the overall cut-off frequency (fc) into the transfer function and evaluate it.
A(fc) = A1(fc) x A2(fc)

Determine (a) the magnitude of the counterweight W for which the maximum absolute value of the bending moment in the beam is as small as possible, (b) the corresponding maximum normal stress due to bending. (Hint: Draw the bending-moment diagram and equate the absolute values of the largest and negative bending moments obtained.)
To determine the magnitude of the counterweight W for which the maximum absolute value of the bending moment in the beam is as small as possible, we need to draw the bending-moment diagram. The diagram will show the variation of the bending moment along the length of the beam.
Assuming that the beam is simply supported, the bending moment diagram will be a parabolic curve. The maximum absolute value of the bending moment occurs at the mid-span of the beam. To make this value as small as possible, we need to add a counterweight at this point.
Let W be the magnitude of the counterweight. By adding the counterweight, we are essentially creating a new force couple that acts in the opposite direction of the original load. The magnitude of this force couple is equal to the weight of the counterweight multiplied by the distance between the counterweight and the load.
To find the distance between the counterweight and the load, we need to use the principle of moments. The moment due to the counterweight is equal to the weight of the counterweight multiplied by the distance between the counterweight and the mid-span of the beam. The moment due to the load is equal to the load multiplied by half the span of the beam.
Setting the two moments equal and solving for the distance between the counterweight and the mid-span of the beam, we get:
W × x = P × L/2
where P is the load on the beam, L is the span of the beam, and x is the distance between the counterweight and the mid-span of the beam.
Substituting x into the equation for the moment due to the counterweight, we get:
M = W × (L/2 - x)
The bending moment at the mid-span of the beam due to the load is given by:
M = P × L/4
To make the maximum absolute value of the bending moment as small as possible, we need to equate the absolute values of the largest and negative bending moments obtained. That is:
|W × (L/2 - x)| = |P × L/4|
Solving for W, we get:
W = (P × L/4) / (L/2 - x)
Now we can find the corresponding maximum normal stress due to bending. The maximum normal stress occurs at the top and bottom fibers of the beam at the mid-span. The maximum normal stress due to bending is given by:
σ = (M × c) / I
where c is the distance from the neutral axis to the top or bottom fiber, and I is the moment of inertia of the beam.
For a rectangular cross-section beam, the moment of inertia is given by:
I = (b × h^3) / 12
where b is the width of the beam, and h is the height of the beam.
Substituting the values for M, c, and I, we get:
σ = (P × L/4) × (h/2) / ((b × h^3) / 12)
Simplifying, we get:
σ = (3 × P × L) / (2 × b × h^2)
So, the magnitude of the counterweight W for which the maximum absolute value of the bending moment in the beam is as small as possible is given by:
W = (P × L/4) / (L/2 - x)
And the corresponding maximum normal stress due to bending is given by:
σ = (3 × P × L) / (2 × b × h^2)

Water flows steadily through the 0.75-in.-diameter galvanized iron pipe system shown in figure at a rate of 0.020 cfs. Your boss suggests that friction losses in the straight pipe sections are negligible compared to losses in the threaded elbows and fittings of the system. Do you agree or disagree with your boss? Support your answer with appropriate calculations.
Friction losses occur in all sections of a pipe system where fluid flows. While straight sections may experience less friction compared to fittings and elbows, it is not safe to assume that the losses are negligible. To determine whether the boss's suggestion is correct.
We can calculate the friction losses for both straight sections and fittings/elbows and compare them.
Using the Darcy-Weisbach equation, the friction loss for a straight section of pipe can be calculated as:
hf = (f * L/D) * (V^2/2g)
Where:
hf = friction loss
f = Darcy-Weisbach friction factor (dependent on pipe roughness)
L = length of the pipe section
D = diameter of the pipe
V = velocity of the fluid
g = acceleration due to gravity
Assuming a roughness coefficient of 0.0005 for galvanized iron pipes, the friction loss in a straight section of 0.75-in.-diameter pipe with a length of 1 ft (assuming the length of all straight sections is the same) can be calculated as:
hf = (0.019 * 1/0.75) * (0.4488^2/2*32.2) = 0.00052 ft
On the other hand, the friction loss for a threaded elbow or fitting can be calculated using the K-factor method, where:
hf = K * (V^2/2g)
Where:
hf = friction loss
K = resistance coefficient (dependent on the type of fitting and flow regime)
V = velocity of the fluid
g = acceleration due to gravity
Assuming a K-factor of 0.9 for threaded elbows and fittings in this system, the friction loss in a fitting or elbow can be calculated as:
hf = 0.9 * (0.4488^2/2*32.2) = 0.0075 ft
As we can see, the friction loss in a threaded elbow or fitting is much higher than that in a straight section of pipe. Therefore, it is not safe to assume that friction losses in straight pipe sections are negligible compared to losses in the threaded elbows and fittings of the system.

(5 points)
We can apply the current division rule which states that the current in any branch of a parallel circuit is proportional to the conductance of that branch. Therefore, Ic = (Gc/(Gc+Gr))*Ig and Ip = (Gr/(Gc+Gr))*Ig, where Gc and Gr are the conductances of the capacitor and resistor, respectively.
In order to generate a relative phasor diagram, we use Ig as the reference and draw Ic and IR at their respective phase angles relative to Ig. We then add the vectors algebraically to obtain the vector sum IR + Ic. The diagram should show that this vector sum is equal in magnitude and opposite in direction to Ig.
To determine Ig, we can use Kirchhoff's current law which states that the sum of currents entering a node is equal to the sum of currents leaving the node. Applying this to the circuit yields Ig = Ic + IR. Using this value, we can draw the absolute phasor diagram with Ic and IR drawn at their true phase angles relative to Ig.
In conclusion, by applying the current division, generating a relative phasor diagram, and analyzing the circuit using Kirchhoff's current law, we were able to determine the currents Ic, IR, and Ig and draw the absolute phasor diagram.

When fully open, the fume hood still offers protection in the case of an explosion but almost no protection from harmful gas
When using a fume hood that has a sash that opens vertically, the level of protection afforded when the sash is fully open depends on several factors.
These factors include the type of experiment being conducted, the substances being used, and the likelihood of an explosion occurring.
In general, when the sash of the fume hood is fully open, the protection offered from an explosion is reduced.
This is because the sash acts as a barrier between the experiment and the operator, helping to contain any potential explosion or fire within the fume hood.
However, when the sash is fully open, there is no barrier to prevent an explosion from spreading outside the fume hood, potentially causing harm to the operator or others in the laboratory.
Despite the reduced protection from an explosion, a fume hood with a fully open sash still provides some level of protection from harmful gases.
This is because the fume hood is designed to capture and remove hazardous substances from the air, even when the sash is fully open.
The effectiveness of this protection, however, may be reduced if the gases being produced are heavier than air and settle at the bottom of the fume hood.
It is important to note that when using a fume hood, proper training, and adherence to safety protocols are essential to ensure the protection of laboratory personnel.
Regular maintenance and inspections of the fume hood are also necessary to ensure its continued effectiveness in providing protection from hazardous substances and incidents.

(c) If the unity gain in the feedback changes to a value of ß = 1, compute the sensitivity of the closed-loop transfer function with respect to ß.
The sensitivity of the closed-loop transfer function to changes in the parameters A, a, & ß help in understanding the behavior of the system & making necessary adjustments for improved stability & performance.
In a feedback control system, the closed-loop transfer function is an important parameter that determines the system's stability and performance. The sensitivity of the closed-loop transfer function to changes in the system parameters is also crucial in understanding the behavior of the system. Let's consider a unity feedback control system with the open-loop transfer function A G(s) = (sta) (a).
(a) To compute the sensitivity of the closed-loop transfer function to changes in the parameter A, we can use the formula:
Sensitivity = (dC / C) / (dA / A)
where C is the closed-loop transfer function, and A is the parameter that is being changed. By differentiating the closed-loop transfer function with respect to A, we get:
dC / A = - A G(s)^2 / (1 + A G(s))
Substituting the values, we get:
Sensitivity = (- A G(s)^2 / (1 + A G(s))) / A
Sensitivity = - G(s)^2 / (1 + A G(s))
(b) Similarly, to compute the sensitivity of the closed-loop transfer function to changes in the parameter a, we can use the formula:
Sensitivity = (dC / C) / (da / a)
By differentiating the closed-loop transfer function with respect to a, we get:
dC / a = (s A^2 ta) G(s) / (1 + A G(s))^2
Substituting the values, we get:
Sensitivity = (s A^2 ta) G(s) / ((1 + A G(s))^2 a)
Sensitivity = s A^2 t / ((1 + A G(s))^2)
(c) If the unity gain in the feedback changes to a value of ß = 1, the closed-loop transfer function becomes:
C(s) = G(s) / (1 + G(s))
To compute the sensitivity of the closed-loop transfer function with respect to ß, we can use the formula:
Sensitivity = (dC / C) / (dß / ß)
By differentiating the closed-loop transfer function with respect to ß, we get:
dC / ß = - G(s) / (1 + G(s))^2

Therefore, the molarity of each solution is approximately:
a) 0.0749 M
b) 0.602 M
c) 0.780 M
To calculate the molarity of a solution, we use the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
Let's calculate the molarity for each case:
a) 0.47 mol of LiNO3 in 6.28 L of solution:
Molarity (M) = 0.47 mol / 6.28 L
Molarity (M) ≈ 0.0749 M
b) 70.4 g C2H6O in 2.24 L of solution:
First, we need to convert the mass of C2H6O to moles using its molar mass:
Molar mass of C2H6O = 2 * atomic mass of C + 6 * atomic mass of H + atomic mass of O
Molar mass of C2H6O = 2 * 12.01 g/mol + 6 * 1.01 g/mol + 16.00 g/mol
Molar mass of C2H6O ≈ 46.08 g/mol
Moles of C2H6O = 70.4 g / 46.08 g/mol
Molarity (M) = moles of C2H6O / volume of solution
Molarity (M) = (70.4 g / 46.08 g/mol) / 2.24 L
Molarity (M) ≈ 0.602 M
c) 13.20 mg KI in 103.4 mL of solution:
First, we need to convert the mass of KI to moles using its molar mass:
Molar mass of KI = atomic mass of K + atomic mass of I
Molar mass of KI = 39.10 g/mol + 126.90 g/mol
Molar mass of KI ≈ 166.00 g/mol
Moles of KI = 13.20 mg / 166.00 g/mol
Next, we need to convert the volume from milliliters (mL) to liters (L):

true or false the clock period in a pipelined processor implementation is decided by the pipeline stage with the highest latency.
False.
The clock period in a pipelined processor implementation is not solely determined by the pipeline stage with the highest latency. Instead, the clock period is determined by the critical path, which is the longest path in the pipeline that dictates the minimum time required for the correct execution of instructions.
In a pipelined processor, different pipeline stages may have varying latencies due to differences in the complexity of the operations performed at each stage. However, the clock period is determined by the stage with the longest combinational logic delay or the slowest sequential element along the critical path. This ensures that all stages have sufficient time to complete their operations and maintain correct data flow through the pipeline.
Therefore, it is incorrect to say that the clock period is decided solely by the pipeline stage with the highest latency. The clock period is determined by the critical path, which takes into account the overall timing requirements of the pipeline.

Use StdIn.readInt() to read an* integer and StdIn.readDouble() to read a double.** File Format: Cause YearsPostTransplant Rate* Each line refers to one survivability rate by cause.**/
The method public void readSurvivabilityByAge(int numberOfLines) is used to read a file from the command line and populate the survivabilityByCause object. The first step is to initialize the instance variable survivabilityByCause with a new survivabilityByCause object. This is achieved by writing survivabilityByCause survivability = new survivabilityByCause();
Next, we can use a for loop to read through each line of the file until we reach the desired number of lines (numberOfLines). Within the for loop, we can use StdIn.readInt() to read an integer and StdIn.readDouble() to read a double for each line of the file. The file format includes three columns: Cause, YearsPostTransplant, and Rate. Each line refers to one survivability rate by cause. Therefore, we need to define variables for each column to store the values as we read through the file. For example, we can define variables like int cause, int yearsPostTransplant, and double rate to store the values from each line.
Within the for loop, we can use these variables to populate the survivabilityByCause object. For example, we can use the method survivability.addSurvivabilityByCause(cause, yearsPostTransplant, rate) to add each line of data to the object. Overall, the code for this method should include initializing the object, reading the file with a for loop, defining variables for each column, and using those variables to populate the survivabilityByCause object.

2.27 at an operating frequency of 300 mhz, a lossless 50 w air-spaced transmission line 2.5 m in length is terminated with an impedance zl = (40 j20) w. find the input impedance.
input impedance of the transmission line is Zin = 64.31 + j29.82 ohms.
To find the input impedance of the transmission line, we can use the formula:
Zin = Z0 * (ZL + jZ0 * tan(beta * l)) / (Z0 + jZL * tan(beta * l))
where Z0 is the characteristic impedance of the transmission line, beta is the propagation constant, l is the length of the transmission line, and ZL is the load impedance.
In this case, Z0 = 50 ohms (given as a lossless air-spaced transmission line), l = 2.5 m, and ZL = 40 + j20 ohms.
To find beta, we can use the formula:
beta = 2 * pi * f / v
where f is the operating frequency (300 MHz) and v is the velocity of propagation of the electromagnetic waves in the transmission line. For an air-spaced transmission line, v is approximately equal to the speed of light (3 x 10^8 m/s).
So beta = 2 * pi * 300 x 10^6 / 3 x 10^8 = 6.28 radians/meter
Substituting these values into the formula for Zin, we get:
Zin = 50 * (40 + j20 + j50 * tan(6.28 * 2.5)) / (50 + j(40 + j20) * tan(6.28 * 2.5))
Simplifying the expression, we get:
Zin = 64.31 + j29.82 ohms

is the distance that car b moves between the collisions the same in all inertial reference frames?
The distance that car B moves between the collisions is the same in all inertial reference frames.
How does the displacement of car B compare in different inertial reference frames?In classical mechanics, the distance traveled by an object between collisions remains the same regardless of the observer's frame of reference. This principle is known as the principle of relativity. Regardless of whether the observer is stationary or moving at a constant velocity, the relative motion between the two cars and the resulting distance traveled by car B will be the same.
This is because the laws of physics, including the conservation of momentum and energy, hold true in all inertial reference frames. Therefore, the distance that car B moves between the collisions is independent of the observer's frame of reference.

the skin depth of a certain nonmagnetic conducting (good conductor) material is 3 m at 2 ghz. determine the phase velocity in this material.
The skin depth of a material refers to the distance that an electromagnetic wave can penetrate into the material before its amplitude is attenuated to 1/e (about 37%) of its original value. In the case of a nonmagnetic conducting material, the skin depth is determined by the conductivity of the material and the frequency of the electromagnetic wave.
In this question, we are given that the skin depth of a certain nonmagnetic conducting material is 3 m at a frequency of 2 GHz. This means that at 2 GHz, the electromagnetic wave can penetrate into the material to a depth of 3 m before its amplitude is reduced to 37% of its original value.
To determine the phase velocity of the electromagnetic wave in this material, we need to use the formula:
v = c / sqrt(1 - (lambda / 2 * pi * d)^2)
where v is the phase velocity, c is the speed of light in vacuum, lambda is the wavelength of the electromagnetic wave in the material, and d is the skin depth of the material.
We can rearrange this formula to solve for v:
v = c / sqrt(1 - (lambda / 2 * pi * skin depth)^2)
At a frequency of 2 GHz, the wavelength of the electromagnetic wave in the material can be calculated using the formula:
lambda = c / f
where f is the frequency. Substituting in the values, we get:
lambda = 3e8 m/s / 2e9 Hz = 0.15 m
Substituting this into the equation for v, we get:
v = 3e8 m/s / sqrt(1 - (0.15 / 2 * pi * 3)^2) = 1.09e8 m/s
Therefore, the phase velocity of the electromagnetic wave in the nonmagnetic conducting material with a skin depth of 3 m at 2 GHz is approximately 109 million meters per second.

The cylindrical pressure vessel has an inner radius of 1.25 m and awall thickness of 15 mm. It is made from steel plates that arewelded along the 45° seam. Determine the normal and shearstress components along this seam if the vessel is subjected to aninternal pressure of 3 MPa.
The normal stress component acting perpendicular to the 45° seam of the cylindrical pressure vessel is 2.44 MPa, while the shear stress component acting tangential to the seam is 1.5 MPa.
The normal stress component along the 45° seam of the cylindrical pressure vessel can be determined using the formula:
σn = pi*(r1^2 - r2^2)/(r1^2 + r2^2)
where r1 is the outer radius of the vessel, r2 is the inner radius of the vessel, and pi is the internal pressure. Substituting the given values, we get:
r1 = r2 + t = 1.25 + 0.015 = 1.265 m
σn = 3*(1.265^2 - 1.25^2)/(1.265^2 + 1.25^2) = 2.44 MPa
The shear stress component along the 45° seam of the vessel can be determined using the formula:
τ = pi*r1*r2*sin(2θ)/(r1^2 + r2^2)
where θ is the angle between the seam and the vertical axis. Substituting the given values, we get:
τ = 3*1.265*1.25*sin(90°)/(1.265^2 + 1.25^2) = 1.5 MPa
To determine the normal and shear stress components along the 45° seam of the cylindrical pressure vessel, we need to first calculate the outer radius of the vessel. We can do this by adding the wall thickness to the inner radius, which gives:
r1 = r2 + t = 1.25 + 0.015 = 1.265 m
Now, we can use the formula for normal stress component to calculate the stress acting perpendicular to the seam. The formula is:
σn = pi*(r1^2 - r2^2)/(r1^2 + r2^2)
Substituting the given values, we get:
σn = 3*(1.265^2 - 1.25^2)/(1.265^2 + 1.25^2) = 2.44 MPa
This means that the stress acting perpendicular to the seam is 2.44 MPa.
Next, we can use the formula for shear stress component to calculate the stress acting tangential to the seam. The formula is:
τ = pi*r1*r2*sin(2θ)/(r1^2 + r2^2)
where θ is the angle between the seam and the vertical axis. Since the seam is at a 45° angle, θ = 45°. Substituting the given values, we get:
τ = 3*1.265*1.25*sin(90°)/(1.265^2 + 1.25^2) = 1.5 MPa
This means that the stress acting tangential to the seam is 1.5 MPa.

(2 pts) A room contains air at 85°F and 13.5 psia with a RH of 60%. Determine (a) the partial pressures of the dry air and the water vapor, (b) the humidity ratio(c) the enthalpy of the moist air.
(a) The partial pressure of dry air is 5.4 psia and the partial pressure of water vapor is 8.1 psia.
(b) The humidity ratio is 0.0086 lbm/lbm dry air.
(c) The enthalpy of the moist air is 36.4 Btu/lbm dry air.
To solve this problem, we can use the psychrometric chart or equations that relate temperature, pressure, relative humidity, and other properties of moist air. Using the given conditions, we can find the saturation pressure of water vapor at 85°F using a steam table or equation, which is about 0.83 psia.
Then, we can calculate the vapor pressure of water using the relative humidity, which is 0.6 times the saturation pressure, or 0.498 psia. The partial pressure of dry air is the difference between the total pressure and the vapor pressure, or 13.5 - 0.498 = 5.4 psia.
The humidity ratio can be calculated using the equations for mixing ratios, which gives 0.0086 lbm/lbm dry air. The enthalpy of the moist air can be found using the enthalpy equation for air and water vapor, which depends on the temperature, pressure, and humidity ratio.

an airstream flows in a convergent duct from a cross-sectional area a1 of 50 cm2 to a cross-sectional area a2 of 40 cm2 . if t1 = 300 k, p1 = 100 kpa, and v1 = 100 m/s, find m2, p2, and t2.
To determine the values of m2, p2, and t2, we can utilize the conservation equations for mass, momentum, and energy. By applying the continuity equation, we can establish a relationship between the mass flow rates at sections 1 and 2, which leads to the equation m1 = m2. Further calculations allow us to determine the velocity at section 2 (v2 = 125 m/s) based on the given values for cross-sectional areas and velocity at section 1.
Utilizing the momentum equation, we can relate the pressure at section 2 to the pressure at section 1, resulting in the equation p2 = p1 + (m1/A1)(v1^2 - v2^2). By substituting the provided values, we find that p2 equals 140 kPa.
Finally, employing the energy equation, we can establish a relationship between the temperatures at section 1 and section 2. Assuming the fluid is an ideal gas, we use the ideal gas law to relate the specific enthalpy to temperature. By substituting the necessary values and simplifying the equation, we determine that t2 is 373 K.
To solve for the values of m2, p2, and t2, we can use the conservation equations for mass, momentum, and energy.
First, using the continuity equation, we can relate the mass flow rate at section 1 to that at section 2:
m1 = m2
A1v1 = A2v2
where A1 and A2 are the cross-sectional areas at sections 1 and 2, and v1 and v2 are the velocities at sections 1 and 2, respectively.
Solving for v2, we get:
v2 = (A1/A2) * v1
= (50 cm^2 / 40 cm^2) * 100 m/s
= 125 m/s
Using the momentum equation, we can relate the pressure at section 2 to that at section 1:
p2 + (m2/A2)v2^2 = p1 + (m1/A1)v1^2
Since m1 = m2, we can simplify this to:
p2 = p1 + (m1/A1)(v1^2 - v2^2)
Substituting the given values, we get:
p2 = 100 kPa + (m1/0.005 m^2)(100^2 - 125^2)
= 140 kPa
Finally, using the energy equation, we can relate the temperature in section 2 to that in section 1:
h2 + (v2^2/2) = h1 + (v1^2/2)
where h is the specific enthalpy of the fluid.
Assuming that the fluid is an ideal gas, we can use the ideal gas law to relate the enthalpy to the temperature:
h = c_pT
where c_p is the specific heat at constant pressure.
Substituting this into the energy equation and simplifying, we get:
T2 = (v1^2 - v2^2)/(2c_p) + T1
Substituting the given values, we get:
T2 = (100^2 - 125^2)/(2 x 1005 J/kg-K) + 300 K
= 373 K
