1 kg of a fluid expands reversibly according to a linear law from 4.2 bar to 1.4 ban the initial and final volumes are 0.004 m and 0.02 m. The fluid is then coole reversibly at constant pressure, and finally compressed reversibly according to a lar pv = constant back to the initial conditions of 4.2 bar and 0.004 m. Calculate th work done in each process and the net work of the cycle. Sketch the cycle on a p- diagram

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
