Discharge Over a Notch — MOE Lab Tender Details

Discharge Over a Notch

For study of weirs as flow regulation and measurement devices

Experiments
Comprehensive study of flow over weirs, including:
Investigation of head against discharge
Coefficient of discharge
Rectangular and different angled V-notches
Full quantitative analysis possible

The set of weirs clearly demonstrates the use of weirs as simple flow regulators. They allow students to derive, and then experimentally verify, relationships between upstream water level and weir discharge for a variety of different shaped notches
