T104D/C - Computerized Boiling Heat Transfer Apparatus
- Code 957511
T104D – Heat Transfer Apparatus with oscilloscope (optional - code 953037)
1. General
The Computerized Boiling Heat Transfer Apparatus T104D/C (code 957511) has been designed to perform experiments
concerning heat transfer due to convection in a boiling liquid (water).
The computerized version unit allows, thanks to the electronic transducers and suitable software, to display on personal
computer and/or print the tables of results and diagrams of the various experiments.
The unit consists of a vessel containing a quantity of water continuously stirred and heated by a nickel filament. Since this
wire is a leg of an alternate current bridge, the temperature can be measured very accurately.
The second leg of the bridge is used to balance the nickel wire and is immersed in a cooling vessel filled with water.
The unit is supplied with manuals that describe each component of the system, installation and utilization procedures, and
gives many exercises.

In the Computerized Boiling Heat Transfer Apparatus, a pure nickel wire is used as a sample element, which is electrically
heated, and an alternate current bridge to measure the temperature.
A water-cooled constantan resistance is used as a reference value, while an oscilloscope ensures its balance.
The apparatus includes an auxiliary heater to raise the water temperature up to the boiling point and to keep it constant.
