In a 150 MW steam turbine unit operating on an enhanced Rankine cycle, steam is delivered from the boiler to the high pressure turbine at 15 MPa and 500° C. It leaves the high pressure turbine at 2 MPa before being reheated to 500°C, after which it enters a second turbine from which it is exhausted to the condenser at 10 kPa. After leaving the condenser saturated, the condensate is pumped back up to 15 MPa and 50° C to restart the cycle. Assuming an isentropic efficiency of 80% for each expansion
a)Calculate the rates of heat transfer for the boiler and reheater
