Chapter 15, Problem 19P

To determine

To find : The maximum efficiency of heat engine.

Answer to Problem 19P

  $0.34$

Explanation of Solution

Given:

  $T_1=580°\text{C}$

  $T_2=380°\text{C}$

Formula Used :

The efficiency in terms of temperature is given as,

  $n=1-\frac{T_1}{T_2}$

Calculation :

Substituting the values,

  $n=1-\frac{380}{580}$

  $\Rightarrow n=\frac{200}{580}=0.34$

  $\Rightarrow n=0.34$
