A power cycle receives 1120 Btu by heat transfer from a reservoir at 1080o F and discharges energy by heat transfer to a reservoir at 280 o F. The thermal efficiency of the cycle is 68% of that for a reversible power cycle operating between the same reservoirs. For the actual cycle, determine the thermal efficiency and energy discharged to the cold reservoir, in Btu(with sketch)
Determine the thermal efficiency of the cycle and the net specific work. Assume each turbine stage isentropic efficiency to be 99% and assume the FWH is open.
