Recall Problem 1.34, which concerned an ideal diatomic gas taken around a rectangular cycle on a PV diagram. Suppose now that this system is used as a heat engine, to convert the heat added into mechanical work.
(a) Evaluate the efficiency of this engine for the case V2 = 3Vl, P2 2Pl.
(b) Calculate the efficiency of an "ideal" engine operating between the same temperature extremes.
