Air contained in a piston-cylinder assembly undergoes two processes in series as shown in Figure. Please assume ideal gas behavior for the air. The changes are negligibly small. For internal energy change, use the constant specific heat. For the air, use R = 0.2870 kJ/kg-K and k = 1.4. Piston 3 Air 4 2 -169.31 169.31 696.86 -348.43 p, bar 5 348.43 1.5 1.0 0.5 What is the specific work for the overall process, i.e., w1-3, in kJ/kg? 0.0 State 3 Isothermal Process State 2 3 State 1 v, m³/kg Air contained in a piston-cylinder assembly undergoes two processes in series as shown in Figure.
