Thermal Technology Principles
~Conduction Lab Assignment~



Object:


1. To investigate Fourier’s Law for the linear conduction of heat along a simple homogeneous bar.

2. To study the conduction of heat along a composite bar and evaluate the overall heat transfer coefficient.

3. To investigate the effect of a change in the cross-sectional area on the temperature profile along a thermal homogenous conductor.


Apparatus:

The H940 heat conduction unit comprising heating and cooling sections, test section, thermo probes and control box.




















Surface Area of bar:

A = = 490.87mm2

= 0.491m2

Theory:


Plane Wall Conduction

If a plane wall of thickness (x) and area (A) supports a temperature difference (T) then the heat transfer rate per unit time (Q) by conduction through the wall is found to be:-

















If the material of the wall is homogeneous and has a th...
