As shown in the figure below, a reversible power cycle receives energy QH by heat transfer from a hot reservoir at TH and rejec energy Qc by heat transfer to a cold reservoir at Tc. Hot reservoir & TH Boundary- R QH (a) If TH=600 K and Tc-400 K, what is the thermal efficiency? (b) If TH-500°C, Tc-20°C, and Wcycle 200 kJ, what are QH and Qc, each in kJ? (c) If n = 50% and Tc-40°F, what is TH, in °F? (d) If n-40% and TH - 727°C, what is Tc, in °C? Wcycle
