Helium gas goes through a cycle ABCDA (consisting of two isochoric and isobaric lines) as shown in figure Efficiency of this cycle is nearly: (Assume the gas to be close to ideal gas)

A

`15.4%`

B

`9.1%`

C

`10.5%`

D

`12.5%`

Text Solution

Verified by Experts

The correct Answer is:
A
`eta = (p_(0)v_(0))/((f)/(2)(p_(0)v_(0))+(f)/(2)(2p_(0))v_(0)+2p_(0)v_(0)) = (1)/((3)/(2)+3+2) = (200)/(13) = 15.4%`
