A Rankine cycle with reheat and a closed feedwater heater (with its drain cascaded back to the
condenser) has 150 kg/s of superheated steam enters the first stage turbine (isentropic efficiency
is 0.78) at 17.5 MPa, 600°C and expands to 6 MPa. It is then reheated to 600 °C before entering
the second-stage isentropic turbine where it expands to the condenser pressure of 15 kPa. Steam
is extracted from the second-stage turbine at 0.4 MPa and fed to the closed feedwater heater.
The feedwater temperature leaving the closed feedwater heater is equal to 5°C below the
saturation temperature at bleed pressure.
Show the entire process on T-s diagram. Label states, indicate appropriate lines of constant
pressure, and show property values.
