A power cycle operates between a lake's surface water at a temperature of 27 C and water at a depth whose temperature is 12 C. At steady state the cycle develops a power output of 10 kW, while rejecting energy by heat transfer to the lower temperature water at the rate of 14,400 kJ/min.

Homework:
Determine the thermal efficiency of the power cycle.

Determine the maximum efficiency of any such power cycle

I need help on this, thanks.
27 c and 12 C degrees
