3.9 Global warming is being discussed. One argument is that the efficiency of all power plants will decrease because the ambient temperature will increase. In this problem, you the reader are asked to determine whether this argument is correct or a false alarm. Imagine a power plant operat- ing in cycles between the temperatures TH ~ 1300 K and T Assume that during the next 50 years T will increase by AT ~1 K. Examine Fig. 8.3 and note that nu is on an average of order 0.5 and that during 50 years n increases by An ~ 0.1. Show analytically how the efficiency of a power plant (n, not N1) varies with AT, and A nu. In 50 years, will n be greater or smaller than today? 300 K. (T)o nd hiah pro ccure
