Solution :

It is given that :

Thermal coefficient = 0.0045/K

Ambient temperature, \($T_a = 25 - 40^\circ$\)

air velocity, v = 0-5 m/s

Solar radiation, \($G= 400-100 \ W/m^2$\)

\($P=50 \ W$\)

Model calculations :

Cell temperature (\($T_c$\))

\($T_c = T_a + \left(\frac{0.25}{5.7+3.8 \ v_w}\right) G$\)

where \($ v_w - v_a = $\) wind speed / air speed

∴ \($T_c = 2 \pi + \left(\frac{0.25}{5.7+3.8 \times 1}\right) \times 400$\)

   \($T_c = 35.526 ^\circ$\)

\($\Delta T = T_c -25$\)

      = 35.526 - 25

      = 10.526 K

Thermal coefficient = 0.0045 x 10.526

b) Calculate the value of the vibration, v, after a time of t1 second.

c) Calculate the time when the vibration reaches the first maximum and minimum value.

d) Sketch one cycle of the vibration function and indicate the calculated points.

a) The maximum value of the vibrations is 60 mm, representing the amplitude of the sinusoidal function. The angular frequency, 0.45π radians/second, determines the rate at which the vibrations oscillate.

b) To calculate the value of the vibration, v, after a time of t1 seconds, substitute the value of t1 into the given equation.

c) The vibration function completes one full cycle when the argument inside the sine function, 0.45πt - θ, equals 2π. By setting this equation equal to 2π, we can solve for the time at which the vibration reaches its first maximum and minimum value.

d) Sketching one cycle of the vibration function involves plotting the displacement of the motor over time, starting from a point where the vibration is at its maximum. Indicate the calculated points, such as the maximum and minimum values and the time when they occur, on the graph to visually represent the behavior of the vibration.

By understanding the maximum value, angular frequency, value after a given time, and the time of first maximum and minimum, we gain insights into the characteristics and behavior of the mechanical vibrations in the factory.

Answer:

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

Explanation:

From Thermodynamics we remember that thermal efficiency of the ideal Otto cycle (\(\eta_{th}\)), dimensionless, is defined by the following formula:

\(\eta_{th} = 1-\frac{1}{r^{\gamma-1}}\) (Eq. 1)

Where:

\(r\) - Compression ratio, dimensionless.

\(\gamma\) - Specific heat ratio, dimensionless.

Please notice that specific heat ratio under cold air standard conditions is \(\gamma = 1.4\).

If we know that \(r = 8.2\) and \(\gamma = 1.4\), then thermal efficiency of the ideal Otto cycle is:

\(\eta_{th} = 1-\frac{1}{8.2^{1.4-1}}\)

\(\eta_{th} = 0.569\)

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

Answer:

- Work done is 2.39 kJ

- heat transfer is 20.23 kJ/kg

Explanation:    

Given the data in the question;

First we obtain for specific volumes and specific enthalpy from "Table Properties Refrigerant 134a;

Specific Volume v₁ =  0.02547 m³/kg

Specific enthalpy u₁ = 243.78 kJ/kg

Specific Volume V₂ = 0.02846 m³/kg

Specific enthalpy u₂ = 261.62 kJ/kg

p = 8 bar = 800 kPa

Any changes in kinetic and potential energy are negligible.

So we determine the work done by using the equation at constant pressure

]Work done W = p( v₂ - v₁ )

we substitute

W = 800 kPa( 0.02846 m³/kg - 0.02547 m³/kg )

W = 800 kPa( 0.00299 m³/kg )

W = 2.39 kJ

Therefore, Work done is 2.39 kJ

Heat transfer;

using equation at constant pressure

Heat transfer Q = W + ( u₂ - u₁ )

so we substitute

Q = 2.392 kJ + ( 261.62 kJ/kg - 243.78 kJ/kg )

Q = 2.392 kJ +  17.84 kJ/kg )

Q = 20.23 kJ/kg

Therefore, heat transfer is 20.23 kJ/kg

The normal depth of flow for a 300-mm diameter concrete pipe laid on a slope of 1m per 500m and carrying water at the rate of 0.05 cu.m. / s is 0.15 m.

The Manning equation is:

Q = \(1/n * R^2/3 * S * 2/3\)

where:

Q is the flow rate (cu.m. / s)

n is the roughness coefficient

R is the hydraulic radius (m)

S is the slope (m/m)

In this case, the flow rate is 0.05 cu.m. / s, the roughness coefficient is 0.012, and the slope is 1/500.

The hydraulic radius can be calculated as:

R = d/4 = 0.3/4 = 0.075 m

Substituting these values into the Manning equation, we get:

0.05 = 1/0.012 * (0.075)^2/3 * 1/500 * 2/3

Solving for the hydraulic radius, we get:

R = 0.15 m

Step response of the given transfer function can be obtained by considering the input as a unit step function i.e. 1/s. Therefore, the output response for the given transfer function is given by:4 G(s) = s² + 4s + 4On substituting s with (1/s), we get4 G(1/s) = (1/s)² + 4(1/s) + 4G(1/s) = (1/s²) + (4/s) + 4

Therefore, the transfer function becomes G(1/s) = 1/s² + 4/s + 4It is clear from the obtained transfer function that the type of response will be overdamped. This is due to the fact that the poles of the transfer function are real and distinct with both poles in the left half of the S-plane. Final Value Theorem can be applied to find the final value of the step response of the given transfer function.

The Final Value Theorem states that the final value of a transfer function can be found by substituting s=0 in the transfer function. Hence, on substituting s=0 in the transfer function G(1/s), we get: G(1/0) = 1/0² + 4/0 + 4G(1/0) = ∞It is clear from the obtained value that the final value of the step response of the given transfer function will be infinite.

Time Constant can be obtained by finding the inverse of the real parts of the poles of the transfer function. The poles of the transfer function are (-2) and (-2).Hence, the time constant of the given transfer function is given byT₁ = 1/2*2 = 1SecondTherefore, the step response of the given transfer function can be written asY(t) = 1 - (1+4t)e⁻²ᵗ + 4e⁻²ᵗThe obtained step response is overdamped with a final value of infinity and a time constant of 1 second.

The response approaches to steady state value without any overshoot or oscillations. The obtained response indicates that the output becomes stable at a constant value of infinity. Therefore, it can be concluded that the given transfer function is not suitable for systems that require a stable output at a finite value.

The pressure drop in 10 ft of length is 416 lbf/ft².

Pressure drop is a measure of the decrease in pressure as fluid flows through a pipe or conduit. In this case, the pressure drop is specified for a length of 10 ft. The given answer of 416 lbf/ft² indicates the amount of pressure drop experienced over this distance.

When fluid flows through a pipe, it encounters resistance due to factors such as friction between the fluid and the pipe walls. This resistance causes a decrease in pressure along the length of the pipe. The pressure drop is typically measured in units of force per unit area, such as pounds per square foot (lbf/ft²).

The value f 416 lbf/ft² suggests that the pressure drop in 10 ft of length is 416 pounds of force per square foot of area. This means that for every square foot of cross-sectional area in the pipe, the pressure decreases by 416 pounds of force. The pressure drop can vary depending on factors such as the fluid properties, pipe diameter, and flow rate.
