  Length Width Height Swim Area
Flume Dimensions (m) 14.4 3.9 4.0 6.0 X 2.5

Technical Specifications of StreamliNZ Flume
The StreamliNZ flume with a swim channel 6m long, 2.5m wide and 1.5m water depth fitted with 2 x 110 kW motors is expected to perform to the following proposed specifications in the the flow channel:

  • Flume Speed
    Controlled from 0.3 to 2.5 m/s
    Optimal water flow quality operating speed 1.8m/s
  • Flow uniformity
    Velocity accuracy
    < 0.5% nominal velocity across the section
    < 1% nominal velocity along the centre line
    Turbulence 1%
  • Wave height < 25mm at 2.00m/s
  • Pitch of the water surface
    -20mm over 6m at 1.00m/s
    -15mm over 6m at 1.50m/s
    +10mm over 6m at 2.00m/s
  • Effective channel width not influenced by the edge effects 2.3m at 2.00m/s (Angle between axial flow and the vortex line estimated at < 1 degree))
  • Pump efficiency 70% at 3.0m/s
