A power plant using steam as the working fluid operates on a Rankine cycle. The temperature at the condenser exit is 80C and the conditions at the turbine inlet are 500 C and 2000 kPa. Assume all components are reversible. Find: (a) the condenser pressure (kPa); (b) the pump work (kJ/kg) What is the pump inlet condition for a Rankine cycle?); (c) the heat added by the boiler (kJ/kg); (d) the cycle efficiency; (e) the efficiency of a Carnot cycle operating between the same temperature limits.
