The following heat engine operates between heat reservoirs at 750 K and 300 K, respectively, and produces power of 95,000 kW.

(a) If the engine operates all reversible, calculate the η, QH, and QC.

(b) In practice, due to the irreversibility, the efficiency η = 0.35. If QH, TH and TC remain the same, calculate the produced work, lost work Wlost, and total entropy generation (ΔS).
