Unformatted text preview: he ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 15 MPa and 600°C and is condensed in the condenser at a pressure of 10 kP. Some steam leaves the turbine at a pressure of 1.2 MPa and enters the open feedwater heater. Determine the fraction of steam extracted from the turbine and the thermal efficiency of the cycle. Solution: First, we determine the enthalpies at various states: The feedwater heaters are generally well insulated (Q=0), and they do not involve any work interactions (W = 0). where y is the fraction of steam extracted from the turbine & m6 & m1...
