As shown in the figure below, two reversible cycles arranged in series each produce the same net work, Weycle- The first cycle receives energy QH by heat transfer from a hot reservoir at TH - 1000°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 Tand rejects energy Qc by heat transfer to a reservoir at Te- 450°R. All energy transfers are positive in the directions of the arrows. Hot reservoir at T1 RI cycle Reservoir at T R2 cycle Cold reservoir at Te

Need ASAP thank you.

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 - 1000°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 Tand rejects energy Qe by heat transfer to a reservoir at Te - 450°R. All energy transfers are positive in the directions of the arrows. Hot reservoir at T RI W cycle Reservoir at T R2 Weycle Cold reservoir at Te Determine: (2) 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 1000°R and 450°R, respectively. Also, determine the ratio of the net work developed by the single cycle to the net work developed by each of the two cycles, Weycle
