Air is compressed in an insulated system from an initial volume and density of 0.42 m3 and 1.11 kg/m3 respectively, to a final volume of 0.12 m3. During this process, the pressure changes with volume according to the relationship p= a + bV where a = 600 kPa, b = - 1200 kPa/m3 and V is in m3. (a) Plot the process on a pv diagram (b) Find the boundary work, in kJ/kg, (c) Is the work into or out of the system? (d) Find the change in internal energy, in kJ/kg (e) Find the heat transfer, kJ/kg.
