The air standard efficiency of an I.C. engine is given by (where r = Compression ratio and $$\gamma $$ = Ratio of specific heats)
A. $$1 - {{\text{r}}^{\gamma - 1}}$$
B. $$1 + {{\text{r}}^{\gamma - 1}}$$
C. $$1 - \frac{1}{{{r^{\gamma - 1}}}}$$
D. None of these
Answer: Option C
Solution (By Examveda Team)
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
