Introduction,f wind and water owed very little to engineering science, and indeed the early steam engine was a practical reality . the science of thermodynamics was firmly established. In contrast, there is now a vast fund of engineering knowledge behind the present day prime movers.

The equations of heat conduction,used since there may exist temperature gradients in other directions. One-dimensional conduction does not often occur in practice since a body would have to be either perfectly insulated at its edges or so large that conduction would be one-dimensional at the centre.

Forced convection: boundary layer principles,cerned with the type of flow situation or the method of analysis. This chapter shows how the convection coefficient may be determined by an approximate analytical method for simple cases of laminar flow. References to other methods will also be given.

Forced convection: Reynolds analogy and dimensional analysis,owever, these methods have only become possible with the use of the more recent and more powerful generations of digital computer, and at an introductory level the more classical approaches will be followed.

Surround Microphone Techniques, . surface temperature is reduced by the addition of fins, the total heat transfer is increased. In the treatment that follows it is assumed that the convection coefficient is known. The Nusselt numbers of finned surfaces may be determined experimentally.

Natural convection,g of some machine or electrical device, or in the heating of a house or room by a convective heating system. It may also be unintentional, in the loss of energy from a steam pipe, or in the dissipation of warmth to the cold air outside the window of a room.
