A power plant with one closed feedwater heater has a condenser temperature of 45°C, a maximum pressure of 5 MPa, and boiler exit temperature of 900°C. Extraction steam at 1 MPa to the feedwater heater condenses and is pumped up to the 5 MPa feedwater lines 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.
