Calcualte the maximum efficiency of an engine operating between`110^(@)C`and`25^(@)C`.

A

`11.1%`

B

`22.2%`

C

`33.3%`

D

`44.4%`

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum efficiency of an engine working between temperature `T_(2)` and `T_(1)` is given by
`eta=(T_(2)-T_(1))/(T_(2))=(383.293)/(383)=0.222eta=22.2%`
