Determine the enthalpies of air per unit mass (h) at the inlet (h.) and outlet (h₂). Determine the mass flow rate of air, in kg/s. Write the equations that are used in your calculation. Determine the inlet area of the air compressor if the inlet air velocity is 12 m/s, in m². Write an energy balance equation for the compressor in the rate form. Include all the relevant energy forms. Determine the power input to the compressor, in kW. Write the equations that are used in your calculation.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.

You have a wind turbine with a maximum power rating of 5 MW available for use in a wind farm. This turbine can operate in winds ranging from a minimum speed of 2 m/s up to a maximum wind speed of 10 m/s (which is when the turbine produces its maximum power). You have two possible sites available: the first site has a steady wind that always blows at 6 m/s. At the second site, the wind blows at 1 m/s for 50% of the time, and at 10 m/s for the other 50% of the time. a. If maximizing the peak power production is the most important consideration, which site should you choose? What will be the maximum power for a single turbine? b. If maximizing the average power production is the most important consideration, which site should you choose? What would be this average power for a single turbine?

A fountain and a water tank will be powered by water from a nearby lake. The elevations and pipe connections are depicted in the diagram below. The fountain's jet water should reach a height of at least 2.5 m from the nozzle outlet. The tank, on the other hand, is elevated to allow gravity to distribute water. The table below contains the specifications for nozzles, suction and discharge pipes. What is the minimum power input to the pump in kW, assuming negligible minor head losses? Assume that the pump efficiency is 88 percent and the motor efficiency is 95 percent. The fountain's water is returned to the lake via a drainage system.
