Apower cycle operates between a lake’s surface water at a temperature of 25 °c and water at a depth whose temperature is 6 °c. at steady state the cycle develops a power output of 14 kw, while rejecting energy by heat transfer to the lower temperature water at the rate 14,400 kj/min. determine the thermal efficiency of the power cycle, the maximum thermal efficiency for any such power cycle, and whether the power cycle is possible.
