HL 102 Pipe Friction Training Panel Show data sheet (pdf file) Print page
Technical Description

  Four different pipe sections are fitted to a panel. Each section can be individually selected using ball valves. The measuring points are 1m apart. To keep measuring inaccuracies as low as possible, the pressure is measured using annular chambers.

  The trainer is supplied from the water mains. The flow rate is adjusted using valves and measured using a rotameter. The pressure drop over a pipe section is measured using a digital, battery-operated differential manometer.

Learning Objectives / Experiments

Experiments to be performed on the pressure loss in pipes
- Measurement of the difference in pressure on

  various pipe sections
- Effect of varying pipe diameter
- Effect of different materials and surface finishes
- Effect of flow rates
- Comparison of experiment and calculation


* Pressure loss measurements in pipes1
* Operation independent of mains electricity1
* Disturbance-free pressure measurement using

  annular chambers
