Q13// A combined gas turbine-vapor power plant has a net power output of 45 MW. Air enters the compresso of the gas turbine at 100 kPa, 300 K, and is compressed to 1200 kPa. The isentropic efficiency of th compressor is 84%. The condition at the inlet to the turbine is 1200 kPa, 1400 K. Air expands through th urbine, which has an isentropic efficiency of 88%, to a pressure of 100 kPa. The air then passes through th nterconnecting heat-recovery steam generator and is finally discharged at 400 K. Steam enters the turbine o he vapor power cycle at 8 MPa, 400° C, and expands to the condenser pressure of 8 kPa. Water enters th oump as saturated liquid at 8 kPa. The turbine and pump of the vapor cycle have isentropic efficiencies of 9 and 80%, respectively. Determine the mass flow rates of the air and the steam, each in kg/s; the net powe developed by the gas turbine

Q13// A combined gas turbine-vapor power plant has a net power output of 45 MW. Air enters the compressor of the gas turbine at 100 kPa, 300 K, and is compressed to 1200 kPa. The isentropic efficiency of the compressor is 84%. The condition at the inlet to the turbine is 1200 kPa, 1400 K. Air expands through the turbine, which has an isentropic efficiency of 88%, to a pressure of 100 kPa. The air then passes through the interconnecting heat-recovery steam generator and is finally discharged at 400 K. Steam enters the turbine of the vapor power cycle at 8 MPa, 400° C, and expands to the condenser pressure of 8 kPa. Water enters the pump as saturated liquid at 8 kPa. The turbine and pump of the vapor cycle have isentropic efficiencies of 90 and 80%, respectively. Determine the mass flow rates of the air and the steam, each in kg/s; the net power developed by the gas turbine and vapor power cycle, each in MW; and the thermal efficiency. Answ(100.87 kg/s; 15.6 kg/s; 29.03 MW; 15.97 MW; 52.8%)
