HM 150.08 Impact of Jet Apparatus
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Fundamentals of Fluid Mechanics /


The unit comprises a plexiglas tank in which a water jet discharged from a nozzle hits a surface and is deflected. 4 different test shapes with the following deflection angles are included: plate 90°, hemisphere 180°, angled plate 45!, cone 135°. The impact forces at the deflector are measured using scales loaded with weights. 
The water supply is provided either from the laboratory mains or using the HM 150 (closed water circuit).

Learning Objectives / Experiments

A hemisphere, a cone, an angled and a flat plate are provided as deflector:
- Impulse-momentum; direct measurement of impact

- Effect of flow rate and velocity 
- Effect of various deflection angles
