Question: The ocean thermal energy conversion project uses the surface water near tropical islands with a temperature of 2 0 C as the hot temperature reservoir,

The ocean thermal energy conversion project uses the surface water near tropical islands with a temperature of 20C as the hot temperature reservoir, and the water at some depth, with a temperature of 5.0C, as the c old temperature reservoir for a heat engine. What is the maximum possible efficiency of an engine running between those two temperatures?
