Vortex Appartus

Model No: FLUIDMC-27
  • 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.
