The air standard efficiency of an I.C. engine is given by (where r = Compression ratio and $$\gamma $$ = Ratio of specific heats)
Answer & Solution
Correct Answer:
Option
C
The air standard efficiency of an I.C. engine is given by $$1 - \frac{1}{{{r^{\gamma - 1}}}}$$
Where,
r = Compression ratio,
$$\gamma $$ = Ratio of specific heats
Where,
r = Compression ratio,
$$\gamma $$ = Ratio of specific heats
