A reheat cycle with two stages of reheating is executed with steam expanding initially from 200 bar and 540℃. The two re-heater pressures are 40 bars and 10 bars, and the steam leaves each re-heater at 540℃. Condensation occurs at 60℃. Sketch the schematic diagram and TS diagram. For the idealcycleand1kg/s of steam, find 

(a). Q _a and thermal efficiency of the cycle.

(b). For the engine, ignore the pressure drop through the reheater, let the engine operate through the same stages and compute Wnet and thermal efficiency of the engine show the TS diagram 

(c). what is the steam flow rate for an engine output of 20,000 KW?
