Flow Over Weir or Open Channel Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14102

A weir is a fundamental concrete or masonry structure built across an open channel or river to raise the upstream water level and allow excess flow over its crest to the downstream side. Weirs are also extensively used as devices for measuring the rate of flow of water in streams and irrigation channels. This experimental unit is designed to study the hydraulic characteristics and facilitate the calibration of various weir types. The apparatus utilizes a centrifugal pump to circulate water from a sump tank into a flow channel where the interchangeable weir is fitted at the end. Water flowing over the weir is collected and directed into a measuring tank or passed through a calibrated flow meter to determine the discharge, which is essential for calculating the Coefficient of Discharge (Cd).

Objectives: Weir Flow Calibration and Measurement

Objective	Key Metric Investigated	Application in Hydraulic Engineering
Flow Over Weirs	Discharge (Q) vs. Head (H)	Establishing the functional relationship between the measured water head over the weir and the flow rate.
Weir Calibration	Coefficient of Discharge (Cd)	Determining the empirical coefficient for sharp-crested, broad-crested, and ogee-shaped weirs.
Study of Weir Types	Flow Characteristics	Analyzing the differences in flow patterns and energy dissipation for the three supplied weir geometries.
