Air enters a compressor operating at steady state at 0.12 MPa, 300K, and a volumetric flow rate of 8 m^3/min. The air is compressed isothermally and exits at 1.5 MPa. The rate of entropy generation during the process is a constant 0.02 kW/K. Determine the power input, the rate of heat transfer from the compressor, and the isentropic efficiency of the compressor. Neglect any changes in kinetic and potential energy. Assume that air behaves as an Ideal Gas with constant specific heat cp = 1.005 kJ/(kg x K).
