Problem 2.33

A gas contained within a pistoncylinder assembly undergoes three processes in series: Process 12: Constant volume from p1 5 1 bar, V1 5 4 m3 to state 2, where p2 5 2 bar. Process 23: Compression to V3 5 2 m3 , during which the pressurevolume relationship is pV 5 constant. Process 34: Constant pressure to state 4, where V4 5 1 m3 . Sketch the processes in series on pV coordinates and evaluate the work for each process, in kJ.

1. Introduction: Rough Surface in Contact I. Surface of Engineering Materials: Generals  Surfaces have chemical properties, which are different from bulk virgin material. o Most metallic surfaces in air have oxide layers, which change the chemical and mechanical properties of the surfaces.  Surfaces have mechanical properties, which are different from bulk material. o Machining or sliding contact makes strain hardened (or work hardened) layer and highly deformed layer, whose strength are different from bulk.  Real engineering surfaces are rough.
