Thermal Condictivity Apparatus

Model : DY-TCA

 

A. Features

The equipment comprise Heat Conduction specimens, are designed to demonstrate
the application of the Fourier Rate equation to simple steady-state conduction in
one dimension.

The units can be configured as a simple plane wall of uniform material and constant
cross sectional area or as composite plane walls with different materials or changes
in cross sectional area to enable the principles of heat flow by linear conduction to
be investigated.

An electrical console provides electrical power to heaters in the specimens and digital
read-out of the temperature at any one of the selected points along the heat
conducting paths.

Cooling water from a laboratory tap provides a heat sink to maintain a steady
temperature gradient.
