The Ocean Thermal Energy Conversion (OTEC) system in Hawaii utilizes the surface water and deep water as thermal energy reservoirs. Assume the ocean temperature at the surface to be 20oC and at some depth to be 5oC; determine
(a) The maximum possible thermal efficiency achievable by a heat engine.
(b) What-if Scenario: What would the maximum efficiency be if the surface water temperature increased to 25oC?
