Problem $10\mathrm{.}036-$ Ideal otto cycle with variable specific heats

An ideal Otto cycle has a compression ratio of $8.$ At the beginning of the compression process, air is at $95$ kPa and $27C,$ and $750k\frac{J}{k}g$ of heat is transferred to air during the constant$-$volume heat$-$addition process: Take inte account the variation of specific heats with temperature. The gas constant of air is $R=0\mathrm{.}287k\frac{J}{k}g*K.$

Problem $10\mathrm{.}036.$d $-$ Mean effective pressure in variable heat capacity ideal otto cycle

Determine the mean effective pressure for the cycle.

The mean effective pressure for the cycle is $4034\mathrm{.}11($ kPa.
