Consider a combined gas-steam power cycle. the topping cycle is a simple brayton cycle that has a pressure ratio of 7. air enters the compressor at15°c at a rate of 10 kg/s and the gas turbine at 950°c. the bottoming cycle is a reheat rankine cycle between the pressure limits of 6 mpa and 10 kpa. steam is heated in a heat exchanger at a rate of 1.15 kg/s by the exhaust gases leaving the gas turbine and the exhaust gases leave the heat exchanger at 200°c. steam leaves the high-pressure turbine at 1.0 mpa and is reheated to 400°c in the heat exchanger before it expands in the low-pressure turbine. assuming 80 percent isentropic efficiency for all pumps and turbine, determine (a) the moisture content at the exit of the low-pressure turbine, % (b) the steam temperature at the inlet of the high-pressure turbine, °c (c) the net power output and the thermal efficiency of the combined plant. w kw %
