Find the rate of entropy production and determine if the cycle operates irreversibly, reverisbly, or impossibly. The inventor claims that a power cycle operates between hot and cold reservoirs at 1200 K and 400 K, respectively, with Calculate the rate of entropy production for this cycle in kW / K. Enter the answer without units, but with a sign if applicable. This cycle operates irreversibly reversibly impossibly.
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.
