A power 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. Step 1 X Your answer is incorrect. Determine the thermal efficiency of the power cycle. n = 5.8 % Attempts: 2 of 2 used Step 2 Your answer is correct. Determine the maximum thermal efficiency for any such power cycle. nmax = 6.37 %
