Multiple choice question: Water is the working fluid in a Rankine cycle that produces 100 MW of power. Superheated vapor enters the turbine at 70 bar, 540°C and exits at 6 kPa. Saturated liquid enters the pump at 6 kPa. The isentropic turbine efficiency is 84%, and the isentropic pump efficiency is 80%. Cooling water enters the condenser at 20°C and exits at 38°C with no significant change in pressure. What do you need to do to solve the problem? 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?
