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°c at a rate of 25 kg/s and exits at 10 kpa and a quality 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 (a) the net power delivered to the generator by the turbine, (b) the rate of entropy generation within the turbine and the compressor during this process, and (c) the isentropic efficiencies of the compressor and the turbine. solve this problem using variable specific heats (exact treatment).
