A 500 kW compressor is being designed to operate on air in a space where the temperature is 300 K and pressure is 90 kPa. The design volume flow rate is 1.5 m3/s. The desired exit state is 1 MPa, 600 K and velocity of 100 m/s. Assume ideal behavior for the air, variable specific heats and R = 0.287 kJ/kg-K, and the temperature of the surroundings is 300 K.
Determine:
a) The rate of entropy change of the air (answer: 0.026 kW/K)
b) The rate of entropy change of the surroundings (answer: 0.035 kW/K)
c) The rate of entropy generated in kW/K
D) Is the system irreversibile, reversibile, or impossible?
