5 A heat engine is operating on a Carnot cycle and has a thermal efficiency of 55%. The waste heat from this engine is rejected to a nearby lake at 60oF at a rate of 800 Btu/min. Determine (a) the power output of the engine and (b) the temperature of the heat source. We can combine the basic definition of cycle efficiency, , and the cycle relationship between |QH|, |QL|, and |W|, , to eliminate . For this problem, where, and  = 55%, we can find the power output as follows.
