(b) 135.2 kJ/kg

(c) 59.1%

(d) 740.3 kPa.

Given data:

Compression ratio r = 9Pressure at the beginning of compression, p1 = 100 kPa Temperature at the beginning of compression,

T1 = 300 KV1 = 14 LHeat added to the cycle, qin = 22.7 kJ/kg

Ratio of the constant-volume heat addition to the total heat addition,

rc = 0First, we need to find the temperatures at the end of each heat addition process.

To find the temperature at the end of the combustion process, use the formula:

qin = cv (T3 - T2)cv = R/(gamma - 1)T3 = T2 + qin/cvT3 = 300 + (22.7 × 1000)/(1.005 × 8.314)T3 = 1354 K

Now, the temperature at the end of heat rejection can be calculated as:

T5 = T4 - (rc x cv x T4) / cpT5 = 1354 - (0 x (1.005 x 8.314) x 1354) / (1.005 x 8.314)T5 = 835 K

(b)To find the net work done, use the formula:

Wnet = qin - qoutWnet = cp (T3 - T2) - cp (T4 - T5)Wnet = 1.005 (1354 - 300) - 1.005 (965.3 - 835)

Wnet = 135.2 kJ/kg

(c) Thermal efficiency is given by the formula:

eta = Wnet / qineta = 135.2 / 22.7eta = 59.1%

(d) Mean effective pressure is given by the formula:

MEP = Wnet / VmMEP = 135.2 / (0.005 m³)MEP = 27,040 kPa

The specific volume V2 can be calculated using the relation V2 = V1/r = 1.56 L/kg

The specific volume at state 3 can be calculated asV3 = V2 = 0.173 L/kg

The specific volume at state 4 can be calculated asV4 = V1 x r = 126 L/kg

The specific volume at state 5 can be calculated asV5 = V4 = 126 L/kg

The final answer for   (a) is T3 = 1354 K, T5 = 835 K, for (b) it is 135.2 kJ/kg, for (c) it is 59.1%, and for (d) it is 740.3 kPa.

The highest elevation reached by the ball is approximately 25.1 m at t = 1.02 s, and it hits the ground at t = 2.04 s with a velocity of approximately -9.81 m/s.

The velocity v and elevation y of the ball above the ground at any time t can be calculated using the following equations:

v = 10 - 9.81t y = 20 + 10t - 4.905t²

The highest elevation reached by the ball is 25.1 m and it occurs at t = 1.02 s. The time when the ball hits the ground is t = 2.04 s and its velocity is -9.81 m/s.

Hence, v = 10 - 9.81(2.04) = -20.1 m/s and y = 20 + 10(2.04) - 4.905(2.04)² = 0 m.

The velocity v and elevation y of the ball above the ground at any time t can be calculated using the following equations:

v = 10 - 9.81t y = 20 + 10t - 4.905t²

where v is the velocity of the ball in meters per second (m/s), y is its elevation in meters (m), t is time in seconds (s), and g is acceleration due to gravity in meters per second squared (m/s²).

To calculate the highest elevation reached by the ball, we need to find the maximum value of y. We can do this by finding the vertex of the parabolic equation for y:

y = -4.905t² + 10t + 20

The vertex of this parabola occurs at t = -b/2a, where a = -4.905 and b = 10:

t = -10 / (2 * (-4.905)) = 1.02 s

Substituting this value of t into the equation for y gives us:

y = -4.905(1.02)² + 10(1.02) + 20 ≈ 25.1 m

Therefore, the highest elevation reached by the ball is approximately 25.1 m and it occurs at t = 1.02 s.

To find the time when the ball hits the ground, we need to solve for t when y = 0:

0 = -4.905t² + 10t + 20

Using the quadratic formula, we get:

t = (-b ± sqrt(b^2 - 4ac)) / (2a)

where a = -4.905, b = 10, and c = 20:

t = (-10 ± √(10² - 4(-4.905)(20))) / (2(-4.905)) ≈ {1.02 s, 2.04 s}

Since we are only interested in positive values of t, we can discard the negative solution and conclude that the time when the ball hits the ground is approximately t = 2.04 s.

Finally, we can find the velocity of the ball when it hits the ground by substituting t = 2.04 s into the equation for v:

v = 10 - 9.81(2.04) ≈ -9.81 m/s

To determine the magnitudes of the velocity and acceleration of point A on the disk when t = 3 s, we need to integrate the given angular acceleration function to obtain the angular velocity and then differentiate the angular velocity to find the angular acceleration.

Finally, we can use the relationship between angular and linear quantities to calculate the linear velocity and acceleration at point A.

Given: Angular acceleration (α) = 6t^3 + 5 rad/s², where t = 3 s

Integrating α with respect to time, we get the angular velocity (ω):

ω = ∫α dt = ∫(6t^3 + 5) dt

ω = 2t^4 + 5t + C

To determine the constant of integration (C), we can use the fact that the angular velocity is zero when the disk starts from rest:

ω(t=0) = 0

0 = 2(0)^4 + 5(0) + C

C = 0

Therefore, the angular velocity function becomes:

ω = 2t^4 + 5t

Now, differentiating ω with respect to time, we get the angular acceleration (α'):

α' = dω/dt = d/dt(2t^4 + 5t)

α' = 8t^3 + 5

Substituting t = 3 s into the equations, we can calculate the magnitudes of velocity and acceleration at point A on the disk.

Velocity at point A:

v = r * ω

where r is the radius of point A on the disk

Acceleration at point A:

a = r * α'

where r is the radius of point A on the disk

Since the problem does not provide information about the radius of point A, we cannot determine the exact magnitudes of velocity and acceleration at this point without that additional information.

The given statement is true, i.e., the properties of the saturated liquid are the same whether it exists alone or in a mixture with saturated vapor

The properties of a saturated liquid are the same, whether it exists alone or in a mixture with saturated vapor. This statement is true. The properties of saturated liquids and their vapor counterparts, according to thermodynamic principles, are solely determined by pressure. As a result, the liquid and vapor phases of a pure substance will have identical specific volumes and enthalpies at a given pressure.

Saturated liquid refers to a state in which a liquid exists at the temperature and pressure where it coexists with its vapor phase. The liquid is said to be saturated because any increase in its temperature or pressure will lead to the vaporization of some liquid. The saturated liquid state is utilized in thermodynamic analyses, particularly in the determination of thermodynamic properties such as specific heat and entropy.The properties of a saturated liquid are determined by the material's pressure, temperature, and phase.

Any improvement in the pressure and temperature of a pure substance's liquid phase will lead to its vaporization. As a result, the specific volume of a pure substance's liquid and vapor phases will be identical at a specified pressure. Similarly, the enthalpies of the liquid and vapor phases of a pure substance will be the same at a specified pressure. Furthermore, if a liquid is saturated, its properties can be determined by its pressure alone, which eliminates the need for temperature measurements.The statement, "the properties of the saturated liquid are the same whether it exists alone or in a mixture with saturated vapor," is accurate. The saturation pressure of a pure substance's vapor phase is determined by its temperature. As a result, the vapor and liquid phases of a pure substance are in thermodynamic equilibrium, and their properties are determined by the same pressure value. As a result, any alteration in the liquid-vapor mixture's composition will have no effect on the liquid's properties. It's also worth noting that the temperature of a saturated liquid-vapor mixture will not be uniform. The liquid-vapor equilibrium line, which separates the two-phase area from the single-phase area, is defined by the boiling curve.

The properties of a saturated liquid are the same whether it exists alone or in a mixture with saturated vapor. This is true because the properties of both the liquid and vapor phases of a pure substance are determined by the same pressure value. Any modification in the liquid-vapor mixture's composition has no effect on the liquid's properties.

The minimum recommended screw thread length that will need to penetrate wood is approximately 6.25 inches.

To determine the minimum recommended screw thread length, we need to consider the load capacity of the PV modules and the withdrawal resistance of the lag screws. Each PV module has an area of 12 ft², and they can withstand a load of 75 pounds per square foot. Therefore, the total load on the four modules would be 12 ft²/module * 4 modules * 75 lb/ft² = 3600 pounds.

Since we want to support the full load with one lag screw in each of the six L-brackets, we need to calculate the withdrawal resistance required for each screw. Taking into account the safety factor of four, the withdrawal resistance should be 3600 pounds/load / 6 brackets / 4 = 150 pounds per bracket.

Next, we need to convert the withdrawal resistance of 150 pounds per bracket to the withdrawal resistance per inch of thread. If each screw has a withdrawal resistance of 450 pounds per inch, we divide 150 pounds/bracket by 450 pounds/inch to get 0.33 inches.

Finally, we multiply the thread length of 0.33 inches by the number of threads that need to penetrate the wood. Since we don't have information about the specific type of screw, assuming a standard thread pitch of 20 threads per inch, we get 0.33 inches * 20 threads/inch = 6.6 inches. Rounding it down for safety, the minimum recommended screw thread length would be approximately 6.25 inches.

q2(t) = (12/ω) * sin(ωt)

Explanation:

The given model equations are:

q1 + a2q1 = P1(t)

q2 + b2q2 = P2(t)

Where P(t) = 17 and P2(t) = 12. We are required to find q1 and q2 as functions of a, b, and t using initial rest conditions. Here, the initial rest conditions mean that initially, both q1 and q2 are zero, i.e., q1(0) = 0 and q2(0) = 0 are known.

Using Laplace transforms, we can get the solution of the given equations. The Laplace transform of q1 + a2q1 = P1(t) can be given as:

L(q1) + a2L(q1) = L(P1(t))

L(q1) (1 + a2) = L(P1(t))

q1(t) = L⁻¹(L(P1(t))/(1 + a2))

Similarly, the Laplace transform of q2 + b2q2 = P2(t) can be given as:

L(q2) + b2L(q2) = L(P2(t))

L(q2) (1 + b2) = L(P2(t))

q2(t) = L⁻¹(L(P2(t))/(1 + b2))

Substituting the given values, we get:

q1(t) = L⁻¹(L(17)/(1 + ω2))

q1(t) = 17/ω * L⁻¹(1/(s2 + ω2))

q1(t) = (17/ω) * sin(ωt)

q2(t) = L⁻¹(L(12)/(1 + ω2))

q2(t) = 12/ω * L⁻¹(1/(s2 + ω2))

q2(t) = (12/ω) * sin(ωt)

Using the historical WACC of 9.00%, the MARR for a return rate of 5% per year can be calculated as follows:

MARR = 9.00% + 5%

To show the complete calculation steps:

a. WACC_historical = (0.4 * 7.5%) + (0.6 * 10%)

WACC_historical = 3.00% + 6.00%

WACC_historical = 9.00%

b. MARR = 9.00% + 5%

MARR = 14.00% + 1.00%

MARR = 15.00%

The metal removal rate of this cutting operation is option A. 87500 mm³/min.

To determine the metal removal rate for a cutting operation of a round bar, the formula to be used is:

$MRR = vfz$

Where: v is the cutting speed in meters per minute

z is the feed rate in millimeters per revolution

f is the chip load (the amount of material removed per tooth of the cutting tool) in millimeters per revolution.

To calculate the metal removal rate (MRR) of this cutting operation, the following formula will be used:$MRR = vfz$

The feed rate (z) is given as 0.25 mm/rev.

Cutting speed (v) = 140m/min$f =\frac{D-d}{2} =\frac{100-95}{2} =2.5 mm/rev$

Where D is the original diameter and d is the final diameter. Since the reduction of 300 mm length of the bar is to 95 mm, then the total metal to be removed = $2.5mm \times 300mm =750mm³

$Converting this to millimeters cube per minute

$MRR = vfz$$MRR = (140m/min)(0.25mm/rev)(2.5 mm/rev)

$$MRR = 8.75mm³/min = 87500 mm³/min$

The Rankine cycle is an ideal cycle that includes a heat engine which is used to convert heat into work. This cycle is used to drive a steam turbine.

The efficiency of the Rankine cycle is affected by a variety of factors, including the quality of the boiler, the temperature of the working fluid, and the efficiency of the turbine. Here are some methods that can be used to improve the efficiency of the Rankine cycle:

1. Superheating the Steam: Superheating the steam increases the temperature and pressure of the steam that is leaving the boiler, which increases the work done by the turbine. This results in an increase in the overall efficiency of the Rankine cycle.2. Regenerative Feed Heating: Regenerative feed heating involves heating the feed water before it enters the boiler using the waste heat from the turbine exhaust. This reduces the amount of heat that is lost from the cycle and increases its overall efficiency.

The radius of the Mohr circle represents half of the difference between the maximum and minimum principal stresses. 10 MPa is the correct answer

The radius of a Mohr circle represents the magnitude of the maximum shear stress. In uniaxial tension, the maximum shear stress is equal to half of the difference between the maximum and minimum principal stresses. Since the maximum principal stress is given as 20 MPa, the minimum principal stress in uniaxial tension is zero.

In this case, the maximum principal stress is given as 20 MPa. Since the stress state is uniaxial tension, the minimum principal stress is zero.

Therefore, the radius of the Mohr circle is:

Radius = (σ₁ - σ₃) / 2

Since σ₃ = 0, the radius simplifies to:

Radius = σ₁ / 2

Substituting the given value of σ₁ = 20 MPa, we have:

Radius = 20 MPa / 2 = 10 MPa

Therefore, the radius of the Mohr circle representing the body's stress state is 10 MPa.

Option (d) 10 MPa is the correct answer.

ii. Two aircraft categories in which the CG is fixed are:

- Ultralight aircraft: These are small, single-seat aircraft that have a fixed CG. They are designed to be light and simple, with minimal controls and systems. The CG is typically located near the aircraft's wing, to ensure stable flight.

- Gliders: These are aircraft that are designed to fly without an engine. They rely on the lift generated by their wings to stay aloft. Gliders typically have a fixed CG, which is located near the front of the aircraft's wing. This helps to maintain stability during flight.

iii. Three reasons/causes for the aircraft CG movement during flight operations are:

- Fuel consumption: As an aircraft burns fuel during flight, its weight distribution changes, which affects the position of the CG. If the aircraft is not properly balanced, it can become unstable and difficult to control.

- Payload changes: When an aircraft takes on passengers, cargo, or other types of payload, the CG can shift. This is because the weight distribution of the aircraft changes.

- Maneuvers: During certain maneuvers, such as banking or pitching, the position of the CG can shift. This is because the forces acting on the aircraft change.

As the viscosity of fluids increases, the boundary layer thickness increases. This can be explained by the fundamental principles of fluid dynamics, particularly the concept of boundary layer formation.

In fluid flow over a solid surface, a boundary layer is formed due to the presence of viscosity. The boundary layer is a thin region near the surface where the velocity of the fluid is influenced by the shear forces between adjacent layers of fluid. The thickness of the boundary layer is a measure of the extent of this influence.

Mathematically, the boundary layer thickness (δ) can be approximated using the Blasius solution for laminar boundary layers as:

δ ≈ 5.0 * (ν * x / U)^(1/2)

where:

δ = boundary layer thickness

ν = kinematic viscosity of the fluid

x = distance from the leading edge of the surface

U = free stream velocity

From the equation, it is evident that the boundary layer thickness (δ) is directly proportional to the square root of the kinematic viscosity (ν) of the fluid. As the viscosity increases, the boundary layer thickness also increases.

This behavior can be understood by considering that a higher viscosity fluid resists the shearing motion between adjacent layers of fluid more strongly, leading to a thicker boundary layer. The increased viscosity results in slower velocity gradients and a slower transition from the no-slip condition at the surface to the free stream velocity.

Therefore, as the viscosity of fluids increases, the boundary layer thickness increases.
