About This Product
Ogee-crested weirs are fixed control structures often used to dam a river, and their downstream side is shaped to improve flow and pass the largest possible discharge. Fitted in the EXPERIMENTAL FLUME FLOW CHANNEL APPARATUS, this weir lets students measure the pressure distribution along its downstream side for different discharges, observe nappe separation and compare theoretical with measured discharge.
Frequently Asked Questions
Q1. How is pressure measured on the ogee-crested weir? Through bores perpendicular to the surface of the downstream side. The heads are read directly on the integrated manometer tubes, which have a measuring range of 290 mmwc.
Q2. What experiments can be carried out with the weir? Hydrodynamic overfall, pressure distribution along the downstream side for different discharges, nappe separation, determination of discharge and head, and comparison of theoretical and measured discharge.
