A Carnot engine whose sinl is at `300K` has an efficiency of `40%`. By how much should the temperature of source be increased so as to increase its efficiency by `50%` of original efficiency.

A

`2750K`

B

`3250K`

C

`3800K`

D

`2500K`

Text Solution

Verified by Experts

The correct Answer is:
D
`eta_(1)=1-(T_(2))/(T_(1)),eta_(2)=1-(T_(2))/(T_(1)^(1))`
Equating `T_(2)` in both the cases.
