Consider a simple Rankine Cycle in which the pressure ratio is 213.33, operating at a mass flow rate of 1.5 kg When the working fluid (water) contains the greatest energy, it is at 1.6MPa and 350 C. (a) If this cycle requires 4374 kW of heat to operate, then what is the isentropic efficiency of the pump? % (b) If water enters the condenser with a quality of 1.0, then what is the isentropic efficiency of the turbine?
