An ideal gas with a known `gamma`, completes a cycle consisting of two isotherms and two isobars. The isothermal processes are executed at temperatures T and `T' (lt T)` and isobaric processes are completed at pressures `P_(0)` and `eP_(0)` [e = base of natural logarithm]. Find the efficiency of the cycle.

Text Solution

Verified by Experts

The correct Answer is:
`(T-T')(gamma-1))/((2gamma-1)T-gammaT')`
