Question

What will be the effect on the efficiency of an Otto cycle having a compression ratio of 7, if the
specific heat at constant volume increases by 1%.​

Answer 1

Answer:

Explanation:

Otto cycle efficiency is given by,

We know,

On taking its log,

Differentiating η with respect to , where ‘r’ is kept constant.

Given,

Therefore there is decrease in 1.026 % of efficiency with increase in 1.6 % specific heat at constant volume.
