A compressor is to be driven by a steam turbine directly trailer that is also driving a generator. The water vapor enters the turbine at 20 MPa and 400 C, at a rate of 4 kg/s, and it comes out at 0.9 kPa and a quality of 0.8. Air enters the compressor at 95 kPa and 200 K at a rate of 5 kg/s, and leaves at 2 MPa and 500 K. Determine a) the net power of the System. b) the rate of entropy generation inside the turbine and compressor during this process.
