Question

It's a thermodynamics question.

(a) A reversible heat engine operates in the indicated cycle on a T-S diagram, in which T is in K and S is in J/K. What is the efficiency of the engine? (I want an explicit number) T(K) A 400 300 500 S(JIK) 1000 (b)A heat engine operates between two finite thermal reservoirs initially at temperatures T1 and T2>T1. The reservoirs have the same total heat capacities, each equal to C. Both reservoirs gradually come to the same final temperature T3, at which time the heat engine stops working. Present an argument to show that T3 2 (T1.T2)/². What maximum work is obtainable from the process?
