An engine cylinder has a piston of area 0.12 m3 and contains gas at a pressure of 2.5 MPa. The gas expands according to a process which is represented by a straight line on a pressure- volume diagram. The final pressure is O.5 MPa. Calculate the work done by the gas on the piston in KJ if the stroke is 0.20 m. *

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.
