Consider an ideal combined reheat and regenerative cycle in which steam enters the high-pressure turbine at 500 lbf/in 2, 700 F, and is extracted to an open feedwater heater at 120 lbf/in.2 with exit as saturated liquid. The remainder of the steam is reheated to 700 F at this pressure, 120 lbf/in 2, and is fed to the low-pressure turbine. The condenser pressure is 2 lbf/in 2. Calculate the thermal efficiency of the cycle and the net work per pound-mass of steam.
