Water is the working fluid in a regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 1600 lb/in² and 1100°F and expands to 120 lb/in.2, where some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.² The remaining steam expands through the second-stage turbine to the condenser pressure of 2 lb/in.² Each turbine stage and both pumps have isentropic efficiencies of 85%. Flow through the condenser, open feedwater heater, and steam generator is at constant pressure. Saturated liquid exits the open feedwater heater at 120 lb/in.² The mass flow rate of steam entering the first stage of the turbine is 2.42x106 lb/h.
