Problem 3: (10 marks) 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 500C at a rate of 25kg/s and exits at 10kPa and a quality of 92%. Air enters the compressor at 98kPa and 295K at a rate of 10 kg 's and exits at 1MPa and 620K. Determine the net power delivered to the generator by the turbine. Note: We need to find cp or the average temperature for air, cp=10AMg.K
