Problem $10\mathrm{.}056-$ Ideal diesel cycle with constant specific heats

An air$-$standard Diesel cycle has a compression ratio of $16$ and a cutoff ratio of $2.$ At the beginning of the compression process, air is at $101\mathrm{.}0$ kPa and $27C.$ Assume constant specific heats. The properties of air at room temperature are $c_p=1\mathrm{.}005k\frac{J}{k}g*K,c_v=0\mathrm{.}718k\frac{J}{k}g*K,R=0\mathrm{.}287k\frac{J}{k}g*K,$ and $k=1\mathrm{.}4.$

Problem $10\mathrm{.}056.$b $-$ Thermal efficiency in constant heat capacity diesel cycle

Determine the thermal efficiency.

The thermal efficiency is $\%.$
