A Rankine cycle power plant has a steam generator exit at 4 MPa, 500C and a condenser exit temperature of 45C. There is no feedwater heater. Find the work input to the pump if the pump efficiency is 80 percent. Find the head transfer in the steam generator. Find the work output of the turbine if the turbine efficiency is 90 percent, the heat transfer in the condenser, and the thermal efficiency of the cycle.
