Concept explainers

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.

Referring to the figure shown below, water contained in a piston-cylinder assembly, initially at 1.5 bar and quality of 20%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is a saturated vapor. The initial height,L1L1, is 0.05 m and the change in height, L2L2, is 0.02 m.
2. A piston-cylinder assembly with stops (see figure) contains 1.54 kg of water initially occupying a volume of 1.25 m at a pressure of 1 bar (State 1). As the water in the assembly is heated, the pressure and temperature in the system remain constant until the piston contacts the stops. In this position (State 2), the quality, x2, is determined to be 92%. Heat continues to be added to the system at a constant volume until the system reaches a pressure of 1.5 bar (State 3).
