PROBLEM 1: An air compressor is designed to compress atmospheric air (assumed to be at 100 kPa, 20°C) to a pressure of 1 MPa. Heat losses to the environment are anticipated to be about equal to 10 - percent of the power input to the compressor. The air enters at 50 m/s where the inlet area is 90 cm? and leaves at 120 m/s through an area of 5cm?. Determine the exit air temperature and the power input to the compressor. Ans: = 117.8°C ; Pinput = 61.83 kW (applied on)
