Description
A sturdy, bench-mounting frame contains a hot water vessel and instrumentation. A controller switches the power to an electric heater to keep a constant ‘bulk’ water temperature inside the vessel. A temperature controller maintains a constant water temperature for the test shape. Precision instruments measure the temperatures at key points, shown on clear multiline displays. The test shapes are of different dimensions and materials to give different heat transfer areas and thermal conductivities. This gives multiple experiments in heat transfer. The student immerses a test shape and measures the transient temperature changes caused by the sudden immersion. They then immerse the other test shapes in turn and compares the results to fi nd how their different surface area, shape and thermal properties affect the heat transfer. The vessel has a large volume of water compared to the test shapes, so their immersion has a negligible affect on the bulk temperature. Students can do tests with or without a computer connected. However, for quicker tests with easier recording of results, we supply their Versatile Data Acquisition System (VDAS®) with this product. The software is intuitive and easy to use, with clear and convenient data display options. It looks similar and works in a similar way for each compliant product. This saves time as students do not have to learn to use new software when changing experiments.
