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.

A piston, 9 cm in diameter, is used to increase the internal pressure in a cylinder from 0 to 50 MPa. The cylinder, which is made of peak-aged aluminum alloy (yield strength = 500 MPa, Kic = 35 MPaVm), has the following dimensions: length = 20 cm, inner diameter = 9 cm and outer diameter =1 1 cm. The piston-cylinder arrangement suffered a malfunction which caused the cylinder to burst.
