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.

Mr Luda wants to understand further about a newly created gas. The gas is initiallyat a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).The gas undergoes a 3-step process in which it is first compressed isothermally toa pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constantpressure back to its original volume (State 3). Finally, the gas is returned to itsoriginal State 1 by cooling at constant volume.a) Sketch the cycle of this system on a P – V diagram.b) Calculate the work done (in kJ) for each process step.c) Determine the total work done for the three-process cycle.d) State whether the work done is on or by the system.
