Discharge Over Notches
Product Code : JA-FMAHLE-9918
The Discharge Over Notches apparatus (SKU JA-FMAHLE-9918) measures flow over interchangeable rectangular and V notches fitted at the end of a flow channel. JaincoLab manufactures this discharge over notches set-up for fluid mechanics and hydraulics practicals in civil and mechanical engineering colleges and polytechnics, where students record the head over each notch with a vernier pointer gauge, time the flow into a measuring tank and work out the coefficient of discharge.
Specifications
The set-up is a self-contained recirculating unit: a centrifugal pump feeds a flow channel from the bottom, the chosen notch is fixed at one end, a pointer gauge with vernier scale reads the water level, and flow control and bypass valves set different flow rates.

Applications of the discharge over notches apparatus
The discharge over notches apparatus is used to relate the head of water over a notch to the flow passing it, so students can find the coefficient of discharge for rectangular and V notches, a standard open-channel flow practical in hydraulics and fluid mechanics laboratories.
- Determining the coefficient of discharge of a rectangular notch
- Determining the coefficient of discharge of 60° and 45° V notches
- Comparing notch shapes at different flow rates set by the control and bypass valves
- Fluid mechanics and hydraulics practicals in civil and mechanical engineering degree and diploma courses
