Solved: A Carnot engine operates with a large hot
Chapter 15, Problem 15.112(choose chapter or problem)
A Carnot engine operates with a large hot reservoir and a much smaller cold reservoir. As a result, the temperature of the hot reservoir remains constant while the temperature of the cold reservoir slowly increases. This temperature change decreases the efficiency of the engine to 0.70 from 0.75. Find the ratio of the final temperature of the cold reservoir to its initial temperature.
