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
