As shown in the figure below, a reversible power cycle receives energy QH by heat transfer from a hot reservoir at TH and rejects energy Qc by heat transfer to a cold reservoir at Tc. Hot reservoir at TH Boundary. R Cold reservoir c at Te W cycle (a) If TH=600 K and Tc = 400 K, what is the thermal efficiency? (b) If TH= 500°C, Tc = 20°C, and Wcycle = 1800 kJ, what are QH and Qc, each in kJ? (c) If n = 60% and Tc = 40°F, what is TH, in °F? (d) If n = 40% and TH = 727°C, what is Tc, in °C?
