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

0.154

B

0.091

C

0.105

D

0.125

Text Solution

Verified by Experts

The correct Answer is:
A
`eta=(p_(0)v_(0))/((f)/(2)(p_0v_0)+(f)/(2)(2p_0)+2p_0v_0)= (1)/((3)/(2)+3+2) (200)/(13)= 15.4%`.
