Product Details

This apparatus is used to study the relationship between the upstream water level (head) and the discharge rate over different sharp-crested weirs, allowing students to compare experimental results with theoretical predictions for both rectangular and triangular (V-notch) profiles. It provides a practical method for investigating open-channel flow measurement techniques and calibrating standard weir shapes commonly used in water management. The trainer is a standalone unit featuring a corrosion-resistant stainless steel water reservoir and a centrifugal pump for continuous water circulation. It includes two interchangeable weir plates—one rectangular and one with a 60-degree V-profile—installed in a channel with perforated inlet plates to minimize turbulence. A movable level gauge with a scale is used to precisely measure the head upstream of the weir, while the actual discharge is determined using a calibrated volumetric tank, enabling direct comparison between measured and calculated flow rates. Its primary application is in civil and environmental engineering education for teaching hydraulic principles related to flow control and measurement in open channels. The key benefit is the hands-on verification of discharge coefficients and the characteristics of flow over different weir shapes, providing students with essential data to understand the factors affecting weir performance in real-world applications such as irrigation canals, wastewater treatment, and river monitoring.
