Both the Fourier Series and the Discrete Fourier Transform are calculated using summation. Explain the key differences in what the inputs each of the Fourier Series and the DFT are AND the requirements the inputs.

Select a subsystem in the passenger car, and explain why the temperature has to be sensed

Knowing: ε=V_4/V_1 =10, ρ=V_2/V_1 =2, and γ=1.4 for the cycle represented in Figure 2, calculate the Diesel cycle efficiency and compare the value with the Carnot efficiency. Draw the V-T, and P-T cycle diagrams.

what are the Sources and calculations of expected errors, uncertainties and delays of wind tunnel test for a vehicle ?

A small community of 50 members in Bidiya has decided to build a mini biogas plant in their area. The waste required for biogas production was collected from different the cows grazing in the farm. Daily consumption of gas per person is a person is 500 liters. Take the specific gravity of the slurry as 1.165 gram/cm 3. For a retention period of sixty-three days design a bio digester. What would be your conclusion regarding the amount of biogas produced in a day, energy generated by the plant in a year, number of cows required to produce the required waste? If 20 more members are joined to this community, what is your suggestion on meeting their daily requirement of gas? Justify your answers with valid data. Also discuss the factors influencing the performance of various stages such as collection stage, anaerobic stage and power generation stage of the entire system.

1- If the velocity head is 250 mm then what is the velocity of the fluid.

2-A tube, open at both ends, is placed into water at constant temperature. How high does the water rise within the tube in mm? The diameter of the tube is 10 mm. Assume the contact angle is zero.

3- You measure air to have a velocity of 45 m/s in a pipe of radius 2 cm. The pipe then expands until its cross-sectional area is 17 cm2 . What is the velocity after the expansion?

4- A dam retains water to a depth 50 % of its height. The height of the wall is 15 m. What is the resultant force on the dam, per meter of dam wall width in kN/m?

Two reservoirs have a difference in height of 10 meters at the free surface. They are connected by two pipes in series; the first tube is 20 m long and has a diameter of 6 cm. The second tube is 10 meters long with a diameter of 10 cm. At the change in tubes, an expander (θ = 20°) is fitted, there are two 90° bends (flanged) in the second section of piping Assuming f = 0.0216 for both tubes, what is the flow rate?

Humans are the most capable beings. Physical, mental, emotional and spiritual potentials of people
or their exergies are very high. But many people are scarred by very little of their exergies and the rest are wasted
he allows me to go. Based on your experiences, physical, mental, emotional and spiritual exergies within 24 hours
draw 4 graphs showing the change over time. How much of the exergies indicated on the charts within 24 hours
and show that you've taken advantage of it. By looking at these charts, you decide that you are evaluating or wasting your life
give me that. How do you think the portion of exergia you benefit from can be increased.
