Which component of the ideal regenerative Rankine cycle loses the greatest amount of work potential where the ideal regenerative Rankine cycle with an open feedwater heater uses water as the working fluid. The turbine inlet is operated at 500psia and 600F and the condenser at 5 psia. Steam is supplied to the open feedwater heater at 40 psia. This cycle rejects heat to a river whose temperature is 60F and the source is at 800F.
