Consider a combined gas–steam power plant that has a net power output of 450 mw. the pressure ratio of the gas-turbine cycle is 14. air enters the compressor at 300 k and the turbine at 1400 k. the combustion gases leaving the gas turbine are used to heat the steam at 8 mpa to 400°c in a heat exchanger. the combustion gases leave the heat exchanger at 460 k. an open feedwater heater incorporated with the steam cycle operates at a pressure of 0.6 mpa. the condenser pressure is 20 kpa. assuming all the compression and expansion processes to be isentropic, determine (a) the mass flow rate ratio of air to steam, (b) the required rate of heat input in the combustion chamber, and (c) the thermal efficiency of the combined cycle.

Asteam power plant is using an ideal regenerative rankine cycle. steamenters the high-pressure turbine at 11,000 kpa and 773.15 k, and the condenser operates at 10 kpa. the steam is extracted from the turbine at 475 kpa to heat the water in an open heater. the water is a saturated liquid afterpassing through the water heater. heat is transferred to the steam in the boiler at a rate of 425mw. determine a) the mass flow rate of steam through the boiler b) the net power output of the plant c) the thermal efficiency of the cycle
