A combined gas turbine-vapor power plant has a net power output of 100 MW. Air enters the compressor of the gas turbine at 100kPa, 300K, and is compressed to 1200kPa. The isentropic efficiency of the compressor is 84%. The conditions at the inlet to the turbine are 1200kPa and 1400 K. Air expands through the turbine, which has an isentropic efficiency of 88%, to a pressure of 100kPa. The air then passes through the interconnecting heat exchanger, and is finally...
