multiple choice question: Water is the working fluid in an ideal Rankine cycle with reheat. Superheated vapor enters the turbine at 12 MPa, 480°C, and the condenser pressure is 8 kPa. Steam expands through the first-stage turbine to 1.2 MPa and then is reheated to 480°C. Assume the pump and each turbine stage has an isentropic efficiency of 85% and 92%, respectively. Determine for the cycle: To solve the problem, what do you need to do? a. analyze each component as a control volume at steady state? b. analyze each component as a closed system at steady state? c. analyze each component as a transient control volume since steam is flowing through it? d. none of the above
