The surface waters of tropical oceans are at a temperature of 30 ∘C while water at a depth of 1200 m is at 3 ∘C. It has been suggested these warm and cold waters could be the heat reservoirs for a heat engine, allowing us to do work or generate electricity from the thermal energy of the ocean.

What is the maximum efficiency possible of such a heat engine?

Respuesta :

Answer:

The maximum efficiency possible of such a heat engine is 8.9%.

Explanation:

Given that,

High temperature = 30°C

Depth = 1200 m

low temperature = 3°C

We need to calculate the maximum efficiency

Using formula of efficiency

[tex]e=1-\dfrac{T_{l}}{T_{h}}[/tex]

Where, [tex]T_{l}[/tex] = low temperature

[tex]T_{h}[/tex] =High temperature

Put the value into the formula

[tex]e=1-\dfrac{3+273}{30+273}[/tex]

[tex]e=0.089[/tex]

The efficiency in percentage,

[tex]e=0.089\times100[/tex]

[tex]e=8.9\%[/tex]

Hence, The maximum efficiency possible of such a heat engine is 8.9%.
