The efficiencty of a carnot engine working between `127^(@) C and 77^(@) C` is

A

0.105

B

0.115

C

0.268

D

0.135

Text Solution

Verified by Experts

The correct Answer is:
C
Here ice point `T_(2)=0^(@)C=0+273 =273 K` and steam point `T_(1)=100^(@)C=100+273=373 K` Efficiency of the carnot engine
`eta=1-(T_(2))/(T_(1))=1-(273)/(373)=(100)/(373)xx100%=26.8%`
