A power cycle operates between a lake's surface water at a temperature of 300l and water at a depth whose temperature is 285 K. at steady state the cycle develops a power output of 10KW, 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 and the maximum thermal efficiency for any such power cycle.
