Ogee Weir Apparatus

The Ogee Weir Apparatus is an educational hydraulic laboratory accessory developed for the practical study of water flow over an ogee-shaped weir under controlled open-channel conditions.

An ogee weir has a smooth curved crest profile designed to guide water efficiently from the upstream section toward the downstream side. Ogee profiles are particularly important in hydraulic engineering because similar crest geometries are widely associated with spillway structures.

The apparatus is designed for installation in a compatible experimental flume, allowing students to observe the behaviour of water as it approaches, passes over, and leaves the curved crest.

One of the primary experiments performed using the apparatus is the study of discharge over an ogee weir. The upstream water head can be measured at different flow conditions and related to the corresponding discharge.

Experimental readings can be used to investigate the Head vs. Discharge relationship. This helps students understand how changes in upstream head influence the quantity of water flowing over the weir.

The curved crest provides a clear demonstration of changes in water depth and flow velocity as the water passes over the control structure.

Students can also observe the water-surface profile around the ogee crest. This provides useful practical understanding of flow acceleration and the hydraulic behaviour of curved spillway-type structures.

Where appropriate measurements are available, experimentally measured discharge can be compared with theoretical values to analyze the hydraulic performance of the weir.

The apparatus is particularly useful for demonstrating concepts related to open-channel hydraulics, weir flow, spillways, discharge measurement, hydraulic control structures, and water-surface profiles.

The Ogee Weir Apparatus provides students with a practical connection between laboratory-scale open-channel experiments and the hydraulic principles applied to real-world spillway and water-control structures.

Micro Technologies supplies Ogee Weir Apparatus and compatible experimental flume accessories for engineering colleges, universities, polytechnic institutes, technical training centres, and hydraulic engineering laboratories.

FAQs

What is the Ogee Weir Apparatus used for?

The apparatus is used to study open-channel flow over an ogee-shaped crest and investigate discharge, upstream water head, water-surface profile, and related hydraulic characteristics.

What is an ogee weir?

An ogee weir is a hydraulic control structure featuring a smooth curved crest profile over which water flows.

Can discharge be determined using the apparatus?

Yes. Upstream water-head measurements and corresponding flow data can be used to investigate discharge over the ogee weir.

Can Head vs. Discharge characteristics be studied?

Yes. Experimental measurements at different flow rates can be used to establish and plot the relationship between upstream head and discharge.

Can the water-surface profile be observed?

Yes. When installed in a compatible transparent experimental flume, students can observe changes in the water-surface profile as water passes over the ogee crest.

Why is an ogee weir important in hydraulic engineering?

Ogee-shaped crest profiles are important for understanding the hydraulic behaviour of spillways and other water-control structures.

Can flow velocity changes be studied?

Yes. Students can observe and analyze how flow conditions change as water approaches and passes over the curved crest.
