The net power output of an ideal regenerative reheat steam cycle is 80 MW. Steam enters the h.p turbine at 80 bar, 500C and expands till it becomes saturated vapour. Some of the steam then goes to an open feedwater heater and the balance is reheated to 400C, after which it expands in the l.p turbine to 0.07 bar. (a) Sketch a (T-s) diagram showing the cycle and clearly label each process. (b) Calculate the reheat pressure. (c) Calculate the dryness fraction. (d) Calculate the feed water fraction. (e) Calculate the cycle efficiency.
