n moles of a diatomic gas has undergone a cyclic process ABC as shown in figure. Temperature at A is `T_(0).` Find

Find out the efficiency

Explanation

`eta=` efficiency of the cycle
`= ("work done by the gas ")/(" heat injected")`
`=eta= (P_(0) V_(0)//2)/(Q _("injected"))xx 100`
`Delta Q_(inj)= Delta Q_(AB) + Delta Q _(BC)`
`=[(5)/(2) nR (2T_(0) -T_(0)) ] + [(5)/(2)nR (2T_(0)) +2P _(0) (2 V _(0) -V_(0))]`
`=19/2 P _(0) V_(0) " "eta=(100)/(19) %`
