A power cycle operating between two thermal reservoirs receives energy QH by heat transfer from a hot reservoir at TH = 2000 K and rejects energy QC by heat transfer to a cold reservoir at TC = 400 K. For each of the following cases determine whether the cycle operates reversibly, operates irreversibly, or is impossible. (a) QH = 1000 kJ, ƞ = 60% (b) QH = 1000 kJ, Wcycle = 850 kJ (c) QH = 1000 kJ, QC =...
