(4) A turbine receives steam at 10 MPa, 600°C and exhaust it at 0.2 MPa. (a) for the ideal Rankine engine, determine the work, steam rate, thermal efficiency, and means effective pressure. (b) for the actual engine, the brake engine efficiency is 84%; the driven generator efficiency is 93% and the rated output of the generator is 30 MW. Estimate the enthalpy ang quality (or temperature) of the exhaust.Compute the combined work, combined heat rate, and the total throttle flow for the rated power.
