There are three heat reservoirs at T1, T2, and T3. And there are two heat engines working among these heat reservoirs.
The first engine receives Q1 and rejects Q2, while producing W1. The second engine receives Q2 and rejects Q3, while producing W2.
The first engine is reversible and the second engine is irreversible. The work produced in the second engine is 80% of that of the first engine.
Express the total cycle work (W1 + W2) and the efficiency of the irreversible engine (or the second engin...
