A fluid at 0.6 bar occupying 0.05 m3 is compressed reversibly to a pressure of 9.9 bar and specific volume of 0.5 m3/kg according to the law pvn = c. The fluid then expands reversibly according to the law pv = c to 2.8 bar. A reversible cooling at constant volume then restores the fluid back to initial state. Calculate the value of n in the process.

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.
