Mr Alvin wanted to find out more about saturated liquid-vapour mixture. He fabricated a piston-cylinder system which contains 1.5 kg of steam at 1.00 MPa and 350°C. The steam is cooled at a constant pressure until half of the mass condenses. a) Deduce the quality of vapour after the cooling process. b) Calculate the volume change for the entire process (in m3). c) Sketch the P – V diagram for this process. d) Determine the work done for this process (in kJ). e) Is it work done on or by the system and why?

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.
