2.5 x 0.08 x 0.25 Metre Flow & Sediment Transport Channel
The FC80 series channels are 80 mm in width, 250 mm high and 2.5 metre length.
The flumes have a built-in re-circulating water supply connected to a digital flow meter for accurate measurements during experimentation.
They have a built-in sediment trap and include sediment (graded sand), a trowel and a rake, for detailed experimentation into sediment transport.
Also included with the flumes are four different models, so students have the ability of immediate experimentation in open channel flow.
The models included are:
• Broad-crested weir
• Sharp-crested weir
• Venturi flume
• Two sluice gates
The channel is made of toughened glass, precision-built to ensure parallel walls and a consistently accurate cross-section along its length. A sturdy steel U-section firmly supports the channel throughout its length. It has a floor-standing frame that supports the working section at a convenient eye-level position for students. A jack raises and lowers the screw support and the digital inclinometer gives an accurate adjustment of the channel angle.
A pump with a control valve, forces water up to flow settling chamber at the upstream end of the channel. This gives smooth, uniform flow, free from entry effects. The downstream end of the channel has a windowed section for visualisation of flow and a settling chamber upon exit. The pump has a stainless steel shaft and urethane impeller, providing excellent wear resistance to sediment in water.
TecQuipment makes a selection of extra (optional) models for use with the flow channels – see Recommended Ancillaries for details: View the ancillary flyer here.
Learning outcomes
- Investigations in fixed and smooth bedform
- Mechanics of sediment transport
- Local (bridge) scour experiments, to understand scour holes and effects on the integrity of a structure
- Two sluice gates for investigations into hydraulic jump, specific energy and the determination of discharge coefficient
- Submerged sharp-crested weir reveals the relationship between head over a weir and discharge
- A broad-crested weir and the effects of changing the profile of the weir
- Uniform flow in an inclined channel with investigations into the Chézy factor and coefficient
- A Venturi flume to indicate the discharge and surface profile, thus the derivation of the discharge coefficient
