Air from the surrounding atmosphere at 100 kPa, 25oC enters a compressor with a velocity of 7 m/s through an inlet of area 0.1 m2. At the exit, the pressure is 600 kPa, the temperature is 150oC, and the velocity is 2m/s. Heat transfer from the compressor to its surrounding occurs at a rate of 3 kW. Determine.
(a) The power input to the compressor.
(b) The rate of entropy generation. Use the PG model for air.
