HM 150.11 Fluid Friction Apparatus
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Fundamentals of Fluid Mechanics /


The panel comprises a pipe network with sub-section that  be isolated individually and one measurement section in which different elements can be inserted. There are 4 water manometers for pressure measurements. The pipe network is made of plastic. Annular chambers enable pressures to be measured with minimum interaction. 
The water supply and flow rate measurements are provided by the HM 150. Alternatively, the arrangement can also be operated from the laboratory mains supply.

Learning Objectives / Experiments
- Pressure loss in pipes and fittings
- Effect of flow velocity on the pressure loss
- Opening characteristics for shut-off devices
- Determination of loss coefficients
- Different flow rate measurement methods
- Comparison of calculation and experiment
