A pistoncylinder assembly contains air modeled as an ideal gas with a constant specific heat ratio, k 5 1.4. The air undergoes a power cycle consisting of four processes in series: Process 12: Constant-temperature expansion at 600 K from p1 5 0.5 MPa to p2 5 0.4 MPa.Process 23: Polytropic expansion with n 5 k to p3 5 0.3 MPa.Process 34: Constant-pressure compression to V4 5 V1.Process 41: Constant-volume heating.Sketch the cycle on a p diagram. Determine (a) the workand heat transfer for each process, in kJ/kg, and (d) thethermal efficiency.
