A heat enegine works on a carnot cycle with a heat sink at a temperature of `2700K`. The efficiency of the engine `10%`. Determine the temperature of heat source.

A

`T=3000K`

B

`T=300K`

C

`T=1000K`

D

`T=30000K`

Text Solution

Verified by Experts

The correct Answer is:
A
Efficiency of carnot Engine
`eta=1-(T_2)/(T_1)`
`(10)/(100)=1-(2700)/(T_1)`
`(2700)/(T_1)=0.9`
`T=3000K`
