A combined gas- steam power plant consists of a pump where 15kg/s saturated liquid water at 10kPa will be compressed until 1000 times and the temperature rises to 80 °C. Later the water will be heated in a heat exchanger where the hot air at 500 °C will enter the heat exchanger until the water at 10MPa becomes 350 °C and the air becomes 25 °C. Later the water vapor will enter the 100% efficient turbine until the pressure drop to 30kPa. Calculate: a) the power of the pump b) the isentropic efficiency of the pump c) mass of the air to ensure the temperature of water increase to 350 °C d) heat gained by the water in the heat exchanger e) power of the turbine f) the quality of water leaving the turbine H20 P AIR HEAT EXCHANGER T A combined gas- steam power plant consists of a pump where 15kg/s saturated liquid water at 10kPa will be compressed until 1000 times and the temperature rises to 80 °C.
