Unformatted text preview: Qc by heat transfer to a reservoir at 400oR. All energy transfers are positive in the directions of the arrows. Determine the following: (a) The intermediate temperature T, in oR, 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 1000oR and 400oR, respectively. Also, determine the net work developed by the single cycle, expressed in terms of the net work developed by each of the two cycles, Wcycle. Figure 2 Question 4 (5.63): The refrigerator shown in Figure 3 operates at steady stat with a coefficient of performance of 4.5 and a power input of 0.8kW. Energy is rejected from the refrigerator...
