In a compressor, air enters at a temperature of 100 kPa and 20 ° C and leaves the compressor at 1200 kPa and 300 ° C. Mass flow rate of the air is 0.65 kg / s and 8 kW heat load is thrown to the environment at 20 ° C from the fins on the compressor surface. Calculate (a) the power input to the compressor, (b) the thermal efficiency, and (c) the entropy generated during this process by accepting the specific heat.
