Consider two reversíble Carnot engines: both operate between temperature reservolrs at TH = 1000 K and Tc = 800 K. The first Is a single engine operating between Ty and Tc; the other consists of two separate heat engines, the first drawing heat from Ty and rejecting heat to a bath at the Intermediate temperature of T; = 900 K, while the second stroke draws heat out of the same (very large) bath at T, and rejects to the reservolr at Tc. The working fluld (ammonia) has a heat capacity ratio of 1.32. The gas pressure is 10 bar at the beginning of the cycle (1000 K), 2.5 bar at the end (800 K), and 5 bar in the middle (900 K). (a) Plot the paths the two engines follow on a pressure-volume diagram (elther on the same plot or on two different ones, your choice, as long as It's clear).
