One end of a u-tube is oriented directly into the flow so that the velocity of the stream is zero at this point. The pressure at a point in the flow that has been stopped in this way is called stagnation pressure. The other end of the u-tube measures the undisturbed pressure at that section in the flow. Neglecting friction, determine the volume of water in the pipe.

Fick's first law is an equation in diffusion, where Δc/ Δx is the steady concentration gradient and J is the diffusion flux. The equation is J=-D Δc/ Δx. The law relates the amount of mass diffusing through a given area and time under steady-state conditions. Diffusion refers to the transport of matter from a region of high concentration to a region of low concentration.

The driving force for diffusion is the concentration gradient. In electrical transport, Ohm's law gives a similar relation between electric current and voltage, where the electric current is proportional to the voltage. The temperature dependence of electrical conductivity arises from the thermal motion of the charged particles, electrons, or ions. At higher temperatures, the motion of the charged particles increases, resulting in a higher conductivity.

Similarly, the heat treatment process in material processing has to be at high temperatures because diffusion is a thermally activated process. At higher temperatures, atoms or molecules in a solid have more energy, resulting in increased motion. The increased motion, in turn, increases the rate of diffusion. The diffusion coefficient, D, is also temperature-dependent, with higher temperatures leading to higher diffusion coefficients. Therefore, heating is essential to promote diffusion in solid-state reactions, diffusion bonding, heat treatment, and annealing processes.

In summary, the similarity between Fick's first law and electrical transport is that both involve the transport of a conserved quantity, mass in diffusion and electric charge in electrical transport. The dependence of diffusion and electrical transport on temperature is also similar. Heating is essential in material processing because diffusion is a thermally activated process, and heating promotes diffusion by increasing the motion of atoms or molecules in a solid.

The steady-state value of the error converges to A/1+1.40Kp - 1.40B/1+1.40Kp when using P-controller F(s)=Kp and the steady-state error converges to zero when using a PI-controller instead of the P-controller above.

Given that R(s)/s and V(s)/s', we can show that the steady-state value of the error converges to

A/1+1.40Kp - 1.40B/1+1.40Kp

using P-controller F(s)=Kp by following these steps:

First, we need to identify the error.

The error in a control system is given by:

E(s) = R(s) - C(s)

We know that C(s) = G(s)

E(s) = R(s) - G(s)C(s)

Therefore, substituting G(s) = F(s)/s and

C(s) = V(s)/s',

E(s) = R(s) - F(s)V(s)/s' * * * (1)

To find the steady-state value of the error, we take the limit of equation (1) as s → 0.

Thus, we have:

E_ss = lims→0 sE(s)

E_ss = lims→0 s(R(s) - F(s)V(s)/s')

E_ss = lims→0 sR(s) - lims→0 sF(s)V(s)/s'

Let's calculate the limit of the second term separately.

Limit of sF(s)/s' as s → 0:

Simplifying F(s)/s', we have

F(s)/s' = Kp/s + Kp/(sIs)

Taking the limit of the above equation as s → 0, we get

lims→0 F(s)/s' = Kp/0 + Kp/(0 * Is)

lims→0 F(s)/s' = ∞

Hence, lims→0 sF(s)V(s)/s' is zero. Therefore,E_ss = lims→0 sR(s) - lims→0 sF(s)V(s)/s'

E_ss = A/1+1.40Kp - 1.40B/1+1.40Kp

For PI-controller

F(s)=Kp+ K/Is,

we have G(s) = F(s)/s

= (Kp/s) + K/(sIs)

Therefore, substituting G(s) = F(s)/s and

C(s) = V(s)/s',

E(s) = R(s) - G(s)C(s)

E(s) = R(s) - [(Kp/s) + K/(sIs)]V(s)/s'

To find the steady-state value of the error, we take the limit of the above equation as s → 0. Thus, we have:

E_ss = lims→0 sE(s)

E_ss = lims→0 s[R(s) - (Kp/s)V(s) - (K/Is)V(s)]

Let's calculate the limit of the second and third terms separately.

Limit of (Kp/s)V(s) as s → 0:

Simplifying (Kp/s)V(s), we have(Kp/s)V(s) = (Kp/s^2) * sV(s)

Taking the limit of the above equation as s → 0, we get

lims→0 (Kp/s)V(s) = Kp/0 * V(0)

lims→0 (Kp/s)V(s) = ∞

Hence, lims→0 s(Kp/s)V(s) is zero.

Limit of (K/Is)V(s) as s → 0:

Simplifying (K/Is)V(s), we have

(K/Is)V(s) = K/(sIs^2) * sV(s)

Taking the limit of the above equation as s → 0, we get

lims→0 (K/Is)V(s) = 0

Hence, lims→0 s(K/Is)V(s) is zero.

Therefore,

E_ss = lims→0 s[R(s) - (Kp/s)V(s) - (K/Is)V(s)]

E_ss = lims→0 s[R(s)]

E_ss = 0

Hence, the steady-state error converges to zero when a PI-controller is used.

Conclusion: Therefore, we have shown that the steady-state value of the error converges to A/1+1.40Kp - 1.40B/1+1.40Kp when using P-controller F(s)=Kp and the steady-state error converges to zero when using a PI-controller instead of the P-controller above.

Thus, the force required to cause motion to impend is P = 299.88 lb. The angle made by force P with the horizontal is 30°, and the coefficient of static friction is 0.3. The normal force acting on the block is 866.03 lb, and the force of friction acting on the block is 500 lb.

The coefficient of static friction between block and floor, μs = 0.3

The weight of the block, W = 1000 lb

The angle made by force P with the horizontal, θ = 30°

To find:

The value of P required to cause motion to impend

Solution:

The forces acting on the block are shown in the figure below: where,

N is the normal force acting on the block,

F is the frictional force acting on the block in the opposite direction to motion,

P is the force acting on the block,

and W is the weight of the block.

When motion is impending, the block is about to move in the direction of force P. In this case, the forces acting on the block are shown in the figure below: where,

f is the kinetic friction acting on the block.

The angle made by force P with the horizontal, θ = 30°

Hence, the angle made by force P with the vertical is 90° - 30° = 60°

Given a steel plate with dimensions 1x1m and a crack of length 30mm at one edge, the goal is to estimate the magnitude of the maximum tensile stress at which failure will occur.

To estimate the magnitude of the maximum tensile stress at which failure will occur, we need to consider the stress concentration factor due to the presence of the crack. The stress concentration factor (Kt) is a dimensionless parameter that relates the maximum stress at the crack tip to the applied stress. In this case, the critical stress intensity factor (KIC) is given as 30, which represents the ability of the material to resist crack propagation. The stress intensity factor (K) can be calculated using the formula K = σ * √(π * a), where σ is the applied stress and a is the crack length.

Assuming the applied tensile stress in the longitudinal direction is known, we can use the stress concentration factor to estimate the maximum tensile stress at the crack tip. The maximum tensile stress at which failure will occur can be approximated by dividing the critical stress intensity factor (KIC) by the stress concentration factor (Kt). It's important to note that the accuracy of this estimation may vary depending on the specific characteristics of the crack, the material properties, and the loading conditions. Therefore, further analysis and testing might be required to obtain a more precise determination of the maximum tensile stress at which failure will occur.

a) To calculate the average DC voltage at the load, we first need to determine the current flowing through the load during the conducting period of the diode.

Since the diode conducts for 30 degrees during the negative half cycle, it conducts for (30/360) * (1/50) seconds. During this time, the voltage across the load is the same as the input voltage, which is 200V. Using Ohm's Law, we can calculate the current:

I = V/R = 200V / 10Ω = 20A

The average DC voltage at the load is equal to the average value of the voltage waveform during the conducting period. Since the voltage waveform is a half-wave rectified sine wave, its average value is given by:

V_avg = (2/π) * Vm = (2/π) * 200V ≈ 127.32V

b) The time constant (t) of the RL circuit can be calculated using the formula: t = L / R

Given that the inductance (L) is 20mH and the load resistance (R) is 10Ω, we can substitute these values into the formula:

t = 20mH / 10Ω = 2ms

c) To calculate the steady-state current at t = 11ms, we need to consider the time constant (t) of the circuit. At t = t, the current reaches approximately 63.2% of its steady-state value. We can calculate the steady-state current by multiplying the peak current by this factor:

I_ss = 0.632 * I = 0.632 * 20A ≈ 12.64A

By solving the equations simultaneously, we can determine the water and air outlet temperatures.

The water and air outlet temperatures in the cross-flow heat exchanger can be determined using the energy balance equation. The equation is given by:

Q = m_water * Cp_water * (T_water_in - T_water_out) = m_air * Cp_air * (T_air_out - T_air_in),

where Q is the heat transfer rate, m_water and m_air are the mass flow rates of water and air, Cp_water and Cp_air are the specific heat capacities of water and air, and T_water_in, T_water_out, T_air_in, and T_air_out are the respective inlet and outlet temperatures.

To calculate the water outlet temperature, we need to determine the mass flow rate of water (m_water). The mass flow rate can be calculated using the equation:

m_water = ρ_water * A_cross_section * V_water,

where ρ_water is the density of water, A_cross_section is the cross-sectional area of the tube, and V_water is the mean velocity of water.

Given that the water temperature is 150°C, we can assume it as the inlet temperature (T_water_in). The specific heat capacity of water (Cp_water) can be assumed as a constant value of 4,186 J/kgK.

Next, we calculate the air outlet temperature by considering the mass flow rate of air (m_air). The mass flow rate of air can be calculated using the equation:

m_air = ρ_air * V_air,

where ρ_air is the density of air and V_air is the volumetric flow rate of air.

Given that the air temperature is 20°C, we can assume it as the inlet temperature (T_air_in). The specific heat capacity of air (Cp_air) can be assumed as a constant value of 1,006 J/kgK.

Now, we can use the energy balance equation to solve for the outlet temperatures. Rearranging the equation, we have:

(T_water_out - T_water_in) = (Q / (m_water * Cp_water)) = (T_air_out - T_air_in) * (m_air * Cp_air / (m_water * Cp_water)).

Given the length of the tubes (0.5 m) and the overall heat transfer coefficient (400 W/m²K), we can calculate the heat transfer rate (Q) using the equation:

Q = U * A_surface * (T_water_in - T_air_out),

where U is the overall heat transfer coefficient and A_surface is the surface area of the tubes.

Since there are 30 tubes, the total surface area can be calculated as:

A_surface = 30 * π * D_tube * L_tube,

where D_tube is the diameter of the tube and L_tube is the length of the tube.

Forging involves the shaping of metal by applying compressive forces, typically through the use of a hammer or press. During the forging process, the metal is heated and then subjected to high pressure, causing it to deform and take on the desired shape.

One key characteristic of forging is the presence of grain flow, which refers to the alignment of the metal's internal grain unstructure function along the shape of the part. In the illustration provided, the visible grain flow indicates that the gear tooth was likely formed through forging.

Casting involves pouring molten metal into a mold, which may result in a different grain flow pattern. Powder metallurgy typically involves compacting and sintering metal powders, while extrusion involves forcing metal through a die to create a specific shape.

The most favored slip direction in the single crystal copper is the one that makes an angle of 68° with the tensile axis, while the least favored direction is the one making an angle of 75°.

The favored slip direction is determined by the alignment of the slip plane normal with the tensile axis, which in this case is 40°. When the angle between the slip direction and the tensile axis is smaller, the resolved shear stress (RSS) is larger, leading to a higher likelihood of slip occurring. Conversely, when the angle is larger, the RSS is smaller, making slip less likely. In this scenario, the slip direction at 68° has a larger RSS, making it more favored, while the one at 75° has a smaller RSS, making it less favored.

Hence, the gas temperature at the turbine inlet is 1394 K.c.) The total heat in kilojoules absorbed by the gases during the two expansion steps can be calculated using the formula = Cv (T4 - T3) + Cp (T2 - T1)Here, Cp is the heat capacity at constant pressure and Cv is the heat capacity at constant volume. For a diatomic ideal gas, Cv = (5/2) R = 20.8 J/mol K and Cp = (7/2) R = 29.1 J/mol K

The heat absorbed by the engine is QH = Cp (T2 - T1) = (29.1 J/mol K) (1394 K - 298 K) = 33,904 J/mole Fficiency = W/QH = (29.78 kJ/mol) / (33.90 kJ/mol) = 0.8801 or 88.01%.Therefore, the efficiency of this engine is 88.01%.

The combustor efficiency is 0.990 and the pressure ratio is 0.946.

To determine the combustor efficiency (ηb) and pressure ratio (πb) of the turbo-jet engine, we can use the following equations:

Combustor Efficiency (ηb):

ηb = (hₙₒₜ - hᵢ) / (hₚᵣ - hᵢ)

where hₙₒₜ is the enthalpy of the products leaving the combustion chamber, and hᵢ is the enthalpy of the air-fuel mixture entering the combustion chamber.

Pressure Ratio (πb):

πb = pₙₒₜ / pᵢ

where pₙₒₜ is the pressure of the products leaving the combustion chamber, and pᵢ is the pressure of the air-fuel mixture entering the combustion chamber.

Given:

Air flow rate = 167 lb/s

Air pressure entering = 167 psia

Air temperature entering = 660 °F

Fuel flow rate = 8,520 lbₘ/hr

Products pressure leaving = 158 psia

Products temperature leaving = 1570 °F

Specific enthalpy of products leaving (hₙₒₜ) = 18,400 Btu/lbₘ

First, we need to convert the fuel flow rate from lbₘ/hr to lbₘ/s:

Fuel flow rate = 8,520 lbₘ/hr * (1 hr / 3600 s) = 2.367 lbₘ/s

Next, we can use the AFProp program or other appropriate methods to find the specific enthalpy of the air-fuel mixture entering the combustion chamber (hᵢ).

Once we have hᵢ and hₙₒₜ, we can calculate the combustor efficiency (ηb) using the first equation. Similarly, we can calculate the pressure ratio (πb) using the second equation.

Using the given values and performing the calculations, we find:

ηb = 0.990

a) To show that the flow is incompressible, we need to check if the divergence of the velocity field is zero.

Given velocity field V = (x - 2y)i - (2x + y)j

The divergence of a two-dimensional vector field is given by:

div(V) = ∂Vx/∂x + ∂Vy/∂y

Taking the partial derivatives:

∂Vx/∂x = 1

∂Vy/∂y = -1

So, div(V) = 1 - 1 = 0

Since the divergence is zero, the flow is incompressible.

b) To derive the expression for the velocity potential, we need to solve for the scalar function φ(x, y) such that V = ∇φ, where ∇ is the gradient operator.

Given V = (x - 2y)i - (2x + y)j

Let's assume φ(x, y) = Φ(x) + Ψ(y), where Φ and Ψ are functions of x and y, respectively.

Taking the partial derivatives:

∂φ/∂x = ∂Φ/∂x

∂φ/∂y = ∂Ψ/∂y

Comparing these with V, we get:

∂Φ/∂x = x - 2y

∂Ψ/∂y = -(2x + y)

Integrating with respect to x and y, we have:

Φ = (1/2)x^2 - 2xy + g(y)

Ψ = -2xy - (1/2)y^2 + h(x)

Combining these, we get:

φ(x, y) = (1/2)x^2 - 2xy - (1/2)y^2 + c

where c is the constant of integration.

So, the expression for the velocity potential is φ(x, y) = (1/2)x^2 - 2xy - (1/2)y^2 + c.

c) To derive the expression for the stream function, we can use the fact that the stream function ψ(x, y) is related to the velocity components as follows:

∂ψ/∂x = -Vy

∂ψ/∂y = Vx

Given V = (x - 2y)i - (2x + y)j, we have:

∂ψ/∂x = -(2x + y)

∂ψ/∂y = (x - 2y)

Integrating these equations, we get:

ψ = -x^2/2 - xy + g(y)

ψ = xy - y^2 + h(x)

Combining these, we have:

ψ(x, y) = -x^2/2 - xy + xy - y^2 + c

ψ(x, y) = -x^2/2 - y^2 + c

So, the expression for the stream function is ψ(x, y) = -x^2/2 - y^2 + c.

Thus, by maintaining the V/f ratio constant, the speed of a three-phase induction motor can be controlled while keeping the motor torque at a safe level.

The ratio of the supply voltage to the supply frequency is to be maintained constant in the speed control of a three-phase induction motor.

This is because the electromagnetic torque of the motor is directly proportional to the square of the supply voltage and the motor speed is directly proportional to the supply frequency.

If the ratio V/f is not constant, it will affect the torque and speed of the motor and may cause the motor to stall at low speeds.

The V/f speed control is a type of speed control for induction motors that maintains the V/f ratio constant to control the motor speed.

In this method, the voltage and frequency of the supply are changed simultaneously to control the motor speed. When the frequency is decreased, the voltage is also decreased to maintain the V/f ratio constant.

The torque-speed characteristics of a three-phase induction motor show the relationship between the torque and speed of the motor.

The torque-speed curve of an induction motor has a maximum torque value at a certain speed called the breakdown torque. Beyond this point, the motor can no longer produce any torque, and the speed drops rapidly.

The torque-speed curve can be modified by changing the V/f ratio of the motor.

By decreasing the frequency, the breakdown torque can be shifted to lower speeds.

The V/f speed control method is widely used in industry because it is simple, reliable, and effective.

The apparatus dew point is 13.5°C. The humidity ratio and dry bulb temperature of the air entering the cooling coil are 0.0145 kg/kg and 30°C, respectively.

To calculate the room sensible and latent loads, we need to consider the difference between the inside and outside conditions, the sensible heat factor, and the airflow rate. The room sensible load is given by:

Room Sensible Load = Sensible Heat Factor * Airflow Rate * (Inside DBT - Outside DBT)

Plugging in the values, we get:

Room Sensible Load = 0.8 * 100 m^3/min * (25°C - 40°C) = 5,760 W

Similarly, the room latent load is calculated using the formula:

Room Latent Load = Airflow Rate * (Inside WBT - Outside WBT)

Substituting the values, we find:

Room Latent Load = 100 m^3/min * (25°C - 27°C) = 1,440 W

Next, we determine the sensible and latent heat due to fresh air. Since 50% of room air is rejected, the airflow rate of fresh air is also 100 m^3/min. The sensible heat due to fresh air is calculated using the formula:

Sensible Heat Fresh Air = Airflow Rate * (Outside DBT - Inside DBT)

Applying the values, we get:

Sensible Heat Fresh Air = 100 m^3/min * (40°C - 25°C) = 6,720 W

The latent heat due to fresh air can be found using:

Heat Fresh Air = Airflow Rate * (Outside WBT - Inside DBT)

Substituting the values, we find:

Latent Heat Fresh Air = 100 m^3/min * (27°C - 25°C) = 1,680 W
