This experiment has a solid brass disc with an electric heater at its centre and a circular cross section cooling tube around its circumference. It mounts on a base plate with a clear schematic of the experiment layout. The electric heater and thermocouples connect to sockets on the Heat Transfer Experiments Base Unit, which also supplies the cold water feed and drain for the heat sink Students turn on the cooling water flow and adjust the heater power until the experiment reaches equilibrium. At equally spaced radii on the disc, seven thermocouples measure the temperature as the heat conducts radially outwards from the heater. Insulation around the disc reduces heat loss by convection and radiation, so that the results should match the theory for simple radial conduction only.
