Question

A heat engine works between source and sink temperature 150c and 30c respectively .The efficiency of heat engine may be

Answer 1

Answer:

Efficiency of the heat engine may be 28.4%

Explanation:

As we know that efficiency of heat engine is defined as

$\eta = 1 - \frac{T_2}{T_1}$

here we know that

$T_2 = 30 + 273$

$T_2 = 303 K$

$T_1 = 150 + 273$

$T_1 = 423 K$

now we know that

$\eta = 1 - \frac{303}{423}$

$\eta = 0.284$
