Q2: Consider a steam power plant operating on the ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at MPa and 600°C and is condensed in the condenser at a pressure of 10 kPa. Some steam leaves the turbine at a pressure of 1.2 MPa and enters the open Teedwater heater. Determine the fraction of steam extracted from the turbine and the thermal efficiency of the cycle.
