A reversible power cycle whose thermal efficiency is 40% receives 50 kJ by heat transfer from a hot reservoir at 600 K and rejects energy by heat transfer to a cold reservoir at temperature TC. Determine the energy rejected, in kJ, and TC, in K.

    thermal efficiency = 40%

    efficiency = (T₂ - T₁) / T₂ where T₂ is temperature of hot reservoir and T₁ is temperature of cold reservoir.

    (600 - T₁) / 600 =.4

    600 - T₁ = 240

    T₁ = 360K

    Energy converted into work = 50 x. 4 = 20 kJ

    heat rejected = 50 - 20 = 30 kJ
