Vortex Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FMP-11324
A low-voltage, variable-speed motor rotates the vessel about its vertical axis.
A speed-control unit, sited away from the main apparatus, controls the speed of rotation.
To produce a forced vortex, students add water to the rotating vessel until it is about half full.
A forced vortex forms.
Students measure the surface profile using the traverse probe.
This forms an annulus into which a continuous water supply is directed.
When the vessel rotates, water passes through the perforations and spirals slowly inwards to a small hole in the centre of the base of the vessel.
The surface falls rapidly towards the centre and produces an air core.
The traverse probe can move both horizontally and vertically, and both axes have linear scales. Students can also measure distribution of total head by replacing the traverse probe with a Pitot tube.
After a few minutes the vortex becomes constant, and students can measure the surface profile using the traverse probe.
