A gas is contained in a vertical piston–cylinder assembly by a piston with a face area of 40 in.2 and weight of 100 lbf. The atmosphere exerts a pressure of 14.7 lbf/in.2on top of the piston. A paddle wheel transfers 3 Btu of energy to the gas during a process in which the elevation of the piston increases by 1 ft. The change in internal energy of the gas is 2.12 Btu. The piston and cylinder are poor thermal conductors,...

0.21 kg of a gas contained within a piston-cylinder assembly undergoes a constant pressure process at 4 bar beginning at v1 = 0.3 m3/kg. For the gas as the system, the moving boundary work is -18 kJ. Determine the initial and final volume of the gas, in m3.
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...
