Through a combustion of a fossil fuel at 35000C, an engine receives energy at a rate of 3000Btu/s to heat a steam to 15000C. There is no energy loss during the combustion process, the steam in turn produces 1000Btu/s of work and rejects the remaining energy to the surrounding at 3000C, What is the thermal efficiency of the plant? What is the reversible work and Carnot efficiency? What is irreversibility?

Two reversible cycles are in series, each process doing the same net work, Wcycle. The first cycle receives energy QH by heat transfer from a hot reservoir at 1000°R and energy Q is reinjected by heat transfer to a reservoir at an intermediate temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and reinjects the QC energy by heat transfer to the reservoir at a temperature of 400°R. All energy transferred is positive in the direction of the arrow. Determine: a) the intermediate temperature T, in °R, and the thermal efficiency for each of the two cycles; b) the thermal efficiency of a simple reversible cycle operating between the hot and cold reservoirs at 1000°R and 400°C, respectively. Then determine the net work done by the simple cycle, expressed in terms of the net work done by each of the two cycles, Wcycle.
