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.

Required information Sometimes equations can be developed and practical problems solved by knowing nothing more than the dimensions of the key parameters. For example, consider the heat loss through a window in a building. Window efficiency is rated in terms of R value, which has the unit of ft2-hr-°F/Btu. A certain manufacturer offers a double-pane window with R = 2.5 and also a triple-pane window with R= 3.4. Both windows are 3.5 ft by 5 ft. On a given winter day, the temperature difference between the inside and outside is 45°F. How much heat is lost through the double-pane window? 315 Btu Return to question

An elastic foundation is often used to support heavy machinery that vibrates in such a way to cause problems for the rest of the structure. An elastic foundation with two equal springs each of stiffness k = 600 lbs/in is used to support the equipment of weight W = 1000 lbs shown. The equipment vibrates in such a way that it causes a vertical forcing function P(t) = 100 sin(20t) [lbs]. %3D (a) Draw the degree of freedom for the motion of the machinery.
