Description                                                           Essential Ancillaries
The TecQuipment Vortex Apparatus enables students to                  • Gravimetric Hydraulic Bench (H1)
produce both free and forced vortices, and measure the                     or
vortex water surface profile.
                                                                      • Volumetric Hydraulic Bench (H1D)
The equipment consists of a transparent vessel on a
                                                                           or
support frame, which mounts on a TecQuipment hydraulic
bench (Gravimetric or Volumetric Hydraulic Benches, H1 or             • Suitable water supply and drain
H1D, are available separately). If no hydraulic bench is
available, an external water supply and drain are required.           Essential Services
A low-voltage, variable-speed motor rotates the vessel                Electrical supply:
about its vertical axis. A speed-control unit (included), sited       Earthed a.c. single-phase electrical supply, 220/250 V,
away from the main apparatus, controls the speed of                   50 Hz or 110/115V, 60 Hz
rotation.
To produce a forced vortex, students add water to the                 Operating Conditions
rotating vessel until it is about half full. A forced vortex          Operating environment:
forms. After a few minutes the vortex becomes constant,               Laboratory environment
and students can measure the surface profile using the
traverse probe. The traverse probe can move both                      Storage temperature range:
horizontally and vertically, and both axes have linear scales.        –25ºC to +55ºC (when packed for transport)
Students can also measure distribution of total head by               Operating temperature range:
replacing the traverse probe with a Pitot tube.                       +5ºC to +40ºC
To produce a free vortex, students place a smaller,
perforated transparent cylinder inside the main vessel. This          Specification
forms an annulus into which a continuous water supply is
                                                                      Dimensions:
directed. When the vessel rotates, water passes through
                                                                      Nett: 920 mm x 620 mm x 520 mm

in the centre of the base of the vessel. The surface falls
rapidly towards the centre and produces an air core.                  Weight:
