Product Description

VERTICAL FLOW FROM A TANK

Used to visualise flow around drag bodies and flow phenomena in open channels.

Either a drag body or weir is fixed in the experimental flume. The streamlines are made visible by injecting a contrast medium. The experimental flume is made of transparent material so that the streamlines and the formation of vortices can easily be observed. The water level in the experimental flume can be adjusted via a sluice gate at the inlet and via a weir at the outlet.

There are two weirs and four different drag bodies available for the experiments. A stabiliser ensures an even and non-vortical flow of water.

The experimental unit is positioned easily and securely on the work surface of the base module. The water is supplied. Alternatively, the experimental unit can be operated by the laboratory supply.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
