A power plant with one closed FWH has a condenser temperature of 45?C, a maximum pressure of 5 MPa, and a boiler exit temperature of 900?C. Extraction steam at 1 MPa to the FWH condenses and is pumped up to the 5-MPa feed water line, where all the water goes to the boiler at 200?C. Find the fraction of extraction steam flow and the two specific pump work inputs.
