An adiabatic steam turbine is directly coupled to an adiabatic air compressor and a generator i.e. the compressor and the generator are powered by the steam turbine. Steam at the rate of 25 kg/s enters the turbine at 12 MPa and 520oC (State 1) and exits the turbine with a quality of 92% at 10 kPa (State 2). Air enters the compressor at 98 kPa and 295 K (State 3) and exits at 1000 kPa and 620 K (State 4) at the rate of 10 kg/s. Calculate the net power (MW) delivered to the generator by the turbine.
