Consider an ideal steam regenerative cycle in which steam enters the turbine at 600 lbf/in 2, 700 F, and exhausts to the condenser at 2 lbf/in 2. Steam is extracted from the turbine at 120 lbf/in 2 for an open feedwater heater. The feedwater leaves the heater as saturated liquid. The appropriate pumps are used for the water leaving the condenser and the feedwater heater. Calculate the thermal efficiency of the cycle and the net work per pound-mass of steam.
