Two kilograms of water is contained in a pis- ton/cylinder (Fig. P3.143) loaded with a linear spring and the outside atmosphere. Initially the water is at 200 kPa, V = 0.2 m³. If the piston just hits the upper stops, the volume is 0.8 m³ and. T= 600°C. Heat is now added until the pressure reaches 1.2 MPa. Show the P-V diagram, and find the work and heat transfer for 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.
