An insulated cylinder contains 1kg of water. The cylinder volume is 0.06 metres cubed and contents are held in place by a heavy piston at a pressure of 2 bar. The contents of the cylinder are then heated by an internal heater causing the piston to move up to the cylinder until the volume has increased to 1 metres cubed. 1) find the dryness fraction at the start of the process 2) calculate the final temperature of steam 3) how much heat has been added

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.
