Air in a cylinder-Piston device undergoes a cyclic process. Initially, the air is at P-5 [MPa) and T-350 [C]. Process 1 to 2 is an isothermal expansion from 5 (MPa) to 1 [MPa). Process 2 to 3 is a polytropie compression to 5 [MPa) with a polytropic exponent n=1.3. The cycle gets completed by a constant pressure process from the state 3 to 1. Air properties are R 0.287 [Kj/Kg. K] and k=1.4 and the mass of air in cylinder...

One kg of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.5 MPa, T1 = 227oC. Process 1-2: Constant-temperature expansion until the volume is twice the initial volume. Process 2-3: Constant-volume heating until the pressure is again 0.5 MPa. Sketch the two processes in series on a p-v diagram. Assuming ideal gas behavior, determine (a) the pressure at state 2, in MPa, (b) the temperature at state 3, in oC, and...
