1. 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. a. (a) If TH=1600 K and Te = 400 K, what is the thermal efficiency? b. (b) If TH=500°C, Tc -20°C, and Wevel 1000 kJ, what are Q and Qc, each in kJ? c. (c) If n = 60% and TC 5 40°F, what is TH, in °F? d. (d) If n = 40 % and TH 5 727°C, what is TC, in °C?
