An air compressor operates at steady state with air entering at p1=1 bar, T= 20°C, and exiting at p2= 5 bar. Determine the work and heat transfer per unit of

mass passing through the device, in kJ/kg,if the air undergoes a polytropic process with n = 1.3. Neglect changes in kinetic and potential energy between the inlet and the exit. Use the ideal gas model for air.I| \frac{\dot{W}_{\mathrm{cv}}}{\dot{m}}=-164.2 \mathrm{~kJ} / \mathrm{kg} \frac{\partial_{\mathrm{cv}}}{\dot{m}}=-31 \mathrm{~kJ} / \mathrm{kg}
