Need Help? Read it 7. -1 points OBinPhys7 5.P028 My Notes Ask Your Teacher A proposed ocean thermal-energy conversion (OTEC) system is a heat engine that would operate between warm water (20°C) at the ocean's surface and cooler water (6°C) 1,092 m below the surface. What is the maximum possible efficiency of the system? Need Help?

Within the range of 0°C to 4°C the specific heat of water doubles when

Explanation / Answer

TH = 25 C = (25 + 273) K

TC = 6 C = (6 + 273) K

Efficiency = (TH– TC)/TH x 100%

                  = [(20 + 273) – (6 + 273)]/(20 + 273) x 100%

Eff = (14/293) x 100% = 4.8 %
