Question
A reversible power cycle receives energy QH by heat transfer from a hot reservoir at TH and rejects energy QL by heat transfer to a cold reservoir at TL. (a) If TH = 1200 K and TL = 300 K, what is the thermal efficiency? (b) If TH = 500°C, TL = 20 °C, and Wcycle = 1000 kJ, what are QH and QL, each in kJ? (c) If?= 60% and TL = 40°F, what is TH, in °F? (d) If?= 40% and TH = 727 °C, what is TL, in °C?
