4. A turbine receives steam at 10 MPa, 600 °C, and exhaust it at 0.20 MPa. (a) For the ideal Rankine engine, the brake thermal efficiency is 84%; the driven generator efficiency is 93%, and the rated output of the generator is 30 MW. Estimate the enthalpy and quality (or temperature) of the exhaust. Compute the combined work, combined heat rate, and the total throttle flow for the rated power.
