Extracted text: 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 7 Boundary- W cycle Cold reservoir Qc at Te (a) If TH = 1100 K and Tc = 400 K, what is the thermal efficiency? (b) If TH = 500°C, Tc = 20°C, and Weycle = 1000 kJ, what are QH and Qc, each in kJ? (c) If ŋ = 60% and Tc = 40°F, what is TH, in °F? (d) If 7 = 40% and TH = 1027°C, what is Tc, in °C?
