4-1 A steam cycle power system operates on an ideal Rankine cycle with two open feedwater heaters. Steam enters the turbine at 480°C and 20 MPa and exhausts at 10 kPa to the condenser. There are two steam extractions from the turbine - at 1.2 MPa and 0.2 MPa. Steam leaves the feedwater heaters (going to the pumps) as a saturated liquid. Mass flow rate of the steam into the turbine is 20 kg/sec. Determine (a) extractions y and z as a fraction of the total steam mass flow rate, (b) the rate of heat rejected from the condenser (kW), (c) net power output of the plant (in kW) and (d) the overall thermal efficiency
