Assignment Help Mechanical Engineering
Reference no: EM131574982

In all of the problems, indicate your assumptions, draw a schematic diagram (if applicable) and show all your work.

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 pV = 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 each of the processes A and B, (a) sketch the process on p-V coordinates, (b) evaluate the work, in kJ, and (e) evaluate the heat transfer, in kJ.
