A steam power plant operates on a regenerative Rankine cycle. Steam enters the turbine at 6 MPa at 700 ºC and the condenser at 10 kPa. Turbine has isentropic efficiency of 85% and pumps have isentropic efficiency of 90%. Steam is extracted from the turbine at 0.6 MPa to heat the feedwater in an open feedwater heater. Water leaves the open feedwater heater as saturated liquid.
