A steam power plant working on Rankine cycle produces steam in the boiler at a rate of 100 kg/s with enthalpy of 3280 kJ/kg from water whose total heat content is 420 kJ/kg. The plant has Rankine efficiency of 24.65 while pump requires 5 kJ/kg of work. The turbine generates power of

Question

Quizplus · Accepted Answer

The net work done by the cycle is given by the Rankine efficiency multiplied by the heat added. The heat added is the difference in enthalpy between the steam and the water. The net work done is then divided by the mass flow rate to find the power output.
