Required information

An air$-$standard cycle with constant specific heats at room temperature is executed in a closed system with $0\mathrm{.}003kg$ of air and consists of the following three processes:

$1-2v=$ Constant heat addition from $95$kPa and $17C$ to $380$kPa

$2-3$ Isentropic expansion to $95$kPa

$3-1P=$ Constant heat rejection to initial state

The properties of air at room temperature are $c_p=1\mathrm{.}005k\frac{J}{k}g*K,c_V=0\mathrm{.}718k\frac{J}{k}g*K,$ and $k=1\mathrm{.}4.$

Calculate the net work per cycle, in kJ$.($You must provide an answer before moving on to the next part.$)$

The net work per cycle is kJ$.$
