The ocean thermal energy conversion project uses the surface water near tropical islands with a temperature of 20°C as the hot temperature reservoir,and the water at some depth,with a temperature of 5.0°C,as the cold temperature reservoir for a heat engine.What is the maximum possible efficiency of an engine running between those two temperatures?
A)4.7%
B)5.1%
C)7.9%
D)15%
E)30%
