Vortex Appartus
• 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.
• The surface falls rapidly towards the centre and produces an air core.
• Students measure the surface profile using the traverse probe.
• 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.
