Water is the working fluid in an ideal Rankine cycle. The
condenser pressure is 8 kPa, and saturated vapor enters the turbine at (a) 18 MPa and (b) 4 MPa. The net power output of
the cycle is 100 MW. Determine for each case the mass flow
rate of steam, in kg/h, the heat transfer rates for the working
fluid passing through the boiler and condenser, each in kW,
and the thermal efficiency.
