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
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 &
