A steam power plant operates on the ideal Regenerative Rankine cycle and has a net power output of 150 MW. Steam enters the turbine at 10 MPa and 500 C and the condenser at 10 kPa. There are no losses in any of the piping or components. Steam is extracted from the turbine at 0.5 MPa to heat the feedwater in an open feedwater heater (O-FWH). Water leaves the O-FWH as a saturated liquid. Determine the steam mass flow rate through the condenser
