As shown in the figure below, two reversible cycles arranged in series each produce the same net work, Weycle. The first cycle receives energy Qu by heat transfer from a hot reservoir at TH = 2000°R and rejects energy Q 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 rejects energy Qc by heat transfer to a reservoir at Tc = 450°R. All energy transfers are positive in the directions of the arrows. Hot reservoir at TH 22H Reservoir at T RI m vir R2 lc Cold reservoir at Te W cycle W cycle Determine: (a) the intermediate temperature T, in °R, and the thermal efficiency for each of the two power cycles. (b) the thermal efficiency of a single reversible power cycle operating between hot and cold reservoirs at 2000ºR and 450°R. respectively. Also, determine the ratio of the net work developed by the single cycle to the network developed by each of the two cycles, Weycle-
