Rankine cycle and has a net power output of 80 MW. Steam enters the
high-pressure turbine at 10 MPa and 550°C and leaves at 0.8 MPa. Some
steam is extracted at this pressure to heat the feedwater in a closed
feedwater heater. The rest of the steam is reheated to 500°C and is
expanded in the low-pressure turbine to the condenser pressure of 10 kPa.
determine (a) the mass flow rate of steam through the boiler and (b) the
thermal efficiency of the cycle.
