Broad-crested weir formula
WebTRAPEZOIDAL BROAD-CRESTED WEIRS . I . The trapezoidal broad-crested weir (Figure I) is a very common measurement device. Constructio is straightforward in existing concrete-lined canals, requiring only a horizontal sill and an upstream ramp. %his configuration is commonly called a ramp flume or a Replogle flume or weir. http://content.alterra.wur.nl/internet/webdocs/ilri-publicaties/publicaties/pub20/pub20-h1.1.pdf

Sharp-Crested Weir Background A sharp-crested weir consists of a vertical flat plate with a sharp edge at the top (the crest), placed in an open channel so that the liquid must flow over the crest in order to drop into the pool below the weir. Figure 1 below shows a longitudinal section representing flow over a sharp-crested weir. Figure 1.
WebThe Discharge over broad-crested weir formula is known by considering the coefficient of discharge, length, and the head of liquid without the velocity approach and is represented as Q = 1.705*Cd*L* (H^1.5) or Discharge = 1.705*Coefficient of Discharge*Length* (Head of … WebThe equation to determine the flow rate for a Cipolletti (Trapezoidal) Weir is: Where: = Flow Rate in cfs. = Width of the weir crest in feet. = Height of the upstream water above the weir crest in feet.
