This experiment has a thin solid bar with an electric heater (heat source) at one end. It mounts on a base plate with a clear schematic of the experiment layout. The bar has a matt black coating for a consistent and predictable emissivity value. Thermocouples measure the temperature along the surface of the bar at equally spaced intervals. The electric heater and thermocouples connect to sockets on the Heat Transfer Experiments Base Unit.
Heat conducts along the bar and transfers to the local surroundings by natural convection and radiation. Students use initial test results to predict the temperatures and heat flow along the bar.
- To show how heat transfers from the surface of a solid bar or rod
- To show the temperatures on, and heat flow through, the solid bar to its surroundings
