4) A reversible power cycle receives energy Q₁ by heat transfer from a hot reservoir at T₁ and rejects energy Qc by heat transfer to a cold reservoir at Tc. If TH= 1600 K and Tc = 400 K, what is the thermal efficiency? ) If Tµ = 500 °C, Tc = 20 °C, and Wcycle = 1000 kJ, what are Q₁ and Qc each in kJ? If n = 40% and T₁ = 727 °C, what is Tċ in °C?=2
