Fitted in the flume, the weirs are used to relate discharge to upstream head over a broad crest, an ogee crest and four thin-plate profiles of the same height, and the ogee model carries manometer tubes for pressure measurement on the weir. The sluice and radial gates show flow under a gate at different openings, and the venturi flume serves as a flow-measuring constriction in an open channel. Changing the slope between -0.5% and +3% alters the flow depth and velocity along the channel.
Water levels are read with the digital level gauge, and point velocities with the impeller velocity meter or the Pitot static tube, so students can build depth and velocity profiles. The flow channel apparatus is for visualising streamlines around drag bodies, and the pipe network apparatus compares head loss against discharge in series and parallel pipe networks.
Flume specifications
The Experimental Flume (EL-EFFCA-11061) has a flow cross-section of 86 x 300 mm, transparent toughened glass side walls, a 280 litre water tank and a 1 kW centrifugal pump rated for a maximum of 15 m3/h at 21 m head, with stainless steel wetted parts. Each extension element adds 2.5 m of glass-walled channel to reach the maximum length of 5 m.
Most Lab Exports products carry a one-year manufacturer warranty. For engineering equipment, on-site installation can be arranged in certain areas.
Tilting flume questions
Is this a tilting flume?
Yes. The inclination of the experimental flume can be adjusted from -0.5% to +3%, so the bed slope is set for each experiment.
How is the price of a tilting flume worked out?
Prices are quoted on request rather than published. The quotation depends on the channel length (2.5 m, or up to 5 m with the extension element) and on which gates, weirs and instruments are ordered with it, so send the list of EL-EFFCA codes with the enquiry.
What are the four plate weirs?
A rectangular weir (with optional aeration), a Thomson weir with a triangular opening, a Cipoletti weir with a trapezoidal opening and a Rehbock weir with a rectangular opening. All four have stainless steel plates of the same weir height for direct comparison.
