Suppose that 1200 J of heat is used as input for an engine
Chapter 15, Problem 15.33(choose chapter or problem)
Suppose that 1200 J of heat is used as input for an engine under two different conditions. In Figure 15.19a the heat is supplied by a hot reservoir whose temperature is 650 K. In part b of the drawing, the heat flows irreversibly through a copper rod into a second reservoir whose temperature is 350 K and then enters the engine. In either case, a 150-K reservoir is used as the cold reservoir. For each case, determine the maximum amount of work that can be obtained from the 1200 J of heat.
