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 500-degree c at a rate of 25 kg/s and exits at 10 kpa and a quality (or dryness factor) of 0.92. air enters the compressor at 98 kpa and 295 k at a rate of 10 kg/s and exits at 1 mpa and 620 k. determine the net power delivered to the generator by the turbine.
