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.

(i) If TH = 1600 K and Tc = 400 K, what is the thermal efficiency?

(ii) If n = 40% and TH = 727°C, what is Tc, in °C? (Watch "Carnot Engine Example-1" for both)

(iii) If TH= 500°C, Tc = 20°C, and Wcycle = 1000 kJ, what are QH and Qc, each in kJ? (Watch "Carnot

Engine Example-2 or 3")
