Flow Channel

Flow Channel The channel consists of a clear acrylic working section of large depth to width ratio incorporating undershot and overshot weirs at the inlet and discharge ends respectively. Water is fed to the streamlined channel entry via a stilling tank to reduce turbulence. Water discharging from the channel is collected in the volumetric tank of the Hydraulics Bench and returned to the sump for recirculation. A dye injection system incorporated at the inlet to the channel permits flow visualization in conjunction with a graticule on the rear face of the channel. Models supplied with the channel include broad and sharp crested weirs, large and small diameter cylinders and symmetrical and asymmetrical aerofoils which, in conjunction with the inlet and discharge weirs, permit a varied range of open channel and flow visualization demonstrations. Experimental Capabilities: Investigating the variation of friction head along a circular pipe with the mean flow velocity in the pipe Investigating the effects of laminar and turbulent flow regimes Specifications: Dye reservoir capacity: 0.45 litres Width of channel: 15mm Length of channel: 615mm Depth of channel: 150mm Models:            - broad crested weir            - narrow crested weir            - symmetrical aerofoil            - asymmetrical aerofoil            - small cylinder            - large cylinder
