A proposed ocean thermal-energy conversion (OTEC) system is a heat engine that would operate between warm water (24°C) at the ocean's surface and cooler water (4°C) 1,711 m below the surface. What is the maximum possible efficiency of the system? Enter your answer accurate to two decimal places.

Answer:

[tex]\eta = 0.067[/tex]

Explanation:

Efficiency of the engine working between two thermal reservoirs is given by the equation

[tex]\eta = 1 - \frac{T_2}{T_1}[/tex]

[tex]T_2 = 4 degree[/tex]

[tex]T_2 = 4 + 273 = 277 K[/tex]

[tex]T_1 = 24 degree[/tex]

[tex]T_1 = 273 + 24[/tex]

[tex]T_1 = 297 K[/tex]

now by the above equation we can say

[tex]\eta = 1 - \frac{277}{297}[/tex]

[tex]\eta = 0.067[/tex]
