An adiabatic air compressor is to be powered by a direct-coupled adiabatic steam turbine that is also driving a generator. Steam enters the turbine at 12.5 MPa and 500oC at a rate of 20 kg/s and exits at 10 kPa and a quality of 0.9. Air enters the compressor at 98 kPa and 295 K at a rate of 5 kg/s and exits at 1 MPa and 620 K. Using air and steam table, explain the net power delivered to the producer by the turbine and the rate of entropy change within the turbine and the compressor during this process. [The gas constant of air is R=0.287 kJ/(kg.K)].
