Flow over weirs
WebWeir is barrier across the width of a river or stream that define as an obstruction in open channel that water must flow over and is used as an indirect method for obtaining the flow rate based on the weir geometry and head over the weir crest (Abd El-Hady Rady, 2011). Weirs can be broad-crested, short-crested, or sharp-crested. WebThe goal of the experiment was to observe and calculate the experimental and theoretical flow rate and the experimental and theoretical discharge coefficient. 2 Introduction. For …

WebTo ensure critical flow over the crest of the weir, it is important to maintain a “free outfall” over the weir. As long as the flow conditions downstream of the weir do not affect the flow over the weir, a free outfall is maintained. Weirs will back up the flow in the channel or conduit, which may alter the locations of flow entrance or ... Webultrasonic weir flow sensor. A significant advantage that weirs and flumes have over other forms of flow measurement is exceptionally high rangeability: the ability to measure very …
