3. Air occupies a 0.3 m³ piston-cylinder at 150 kPa and 278 K. The piston-cylinder operates on a three-process cycle where from state 1 to state 2 the pressure constant and V2 = 1.4 V1. From state 2 to 3 the compression is reversible adiabatic until V3 = V1, and the temperature at state 3 is 450 K. A constant-volume process completes the cycle. Sketch the cycle on a p-V diagram and determine the network and heat flows for the cycle.
