Broad Crested Weir
Product Code : EL-EFFCA-11070
The Broad Crested Weir accessory from Lab Exports is a cuboid-shaped weir body with a sharp edge and optional rounded-edge elements, fitted to the experimental flume to demonstrate free and submerged overfall and the effect of weir edge shape on flow processes.
Specifications
| Weir Body | PVC, cuboid shaped, sharp edges, with sealing lips |
| Additional Elements | 2 nos., for creating rounded edges |
| Dimensions (L x W x H) | 260 x 96 x 120 mm (weir body) |
| Weight | Approx. 5 kg |
Key Features
- Cuboid weir body available with sharp-edged or rounded-edge configurations
- Two additional elements can be fixed to the weir body to create rounded edges
- Clearly demonstrates both free and submerged overfall conditions
- Shows the effect of sharp-edged vs. rounded weir crest on the nappe
- Used with a level gauge to determine discharge coefficient and discharge
- Enables comparison of theoretical and measured discharge values
Applications
The Broad Crested Weir accessory is used with the experimental flume to study broad-crested weir hydraulics, helping students compare sharp-edged and rounded weir crest behaviour, determine discharge coefficients, and validate theoretical discharge calculations against measured results.
