A gas contained within a piston-cylinder assembly undergoes two processes
A gas contained within a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where p1=10 bar, V1= 0.1 m3, U1=400 kJ and p2=1 bar, V2=1.0 m3, U2=200 kJ: Process A. Process from 1 to 2 during which the pressure-volume relation is p.V = constant. Process B: Constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2 Kinetic and potential energy effects can be ignored. For...

2. One lb of air undergoes a power cycle consisting of the following processes: 1->2: constant volume from p1=20 psi, T1=500°R to T2=820°R 2->3: adiabatic expansion to v3 = 1.4 v2 3->1: constant pressure compression Sketch the cycle on a p-v diagram. Assuming ideal gas behavior, determine (a) The pressure at state 2 in psi. (b) The temperature at state 3 in °R. (c) The thermal efficiency of the cycle.

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...

The p-V diagram in the figure shows two paths along which a sample of gas can be taken from state a to state b, where Vb = 5.0V1. Path 1 requires that energy equal to 4.0P1V1 be transferred to the gas as heat. Path 2 requires that energy equal to 10.5p1Vi be transferred to the gas as heat. What is the ratio p2lp1?
