Question

A heat engine has a cold reservoir of 250 K and a hot reservoir of 715 K. What is the maximum efficiency of the engine?

Answer 1

Answer:

0.65

Explanation:

Given Data:

Tc=715K

Th=250K

Find Out: Effeciency=?

Solution:

Effeciency=1-$\frac{Tc}{Th}$

                 =1-250/715

                 =1-0.34

              %maximum effeciency    =0.65
