## Homework Statement

An Engine works within Otto cycle where the compression ratio is 6, and 350 kJ of heat was added to it. Determine the efficiency of the cycle and the work done if Cp/Cv is 1.45

## Homework Equations

Efficiency

_{Otto}= (1- r

^{1-k})

Efficiency (eff.) =Work (W) /Heat Transferred (Q)

## The Attempt at a Solution

Efficiency

_{Otto}= (1- r1-k) ( r is the compression ratio, k is Cp/Cv)

= 1-61-1.45

= 0.5534 =

**55.34% --> The efficiency of the cycle**

W=eff. * Q = 0.5534 * 350

**W=193.72 kJ --> The work done**
