Steam @ 10 MPa, 600 degrees celcius enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is @ 500 degrees celcius, and the condensor pressure is 5 kPa. If the quality at the exit of the second-stage turbine is 90%, determine the cycle thermal efficiency.
