WebZ = side slope (Z horizontal to 1 vertical) of the weir crest H = distance between water surface and the crest, ft (m) Cw = weir coefficient, typically 3.367 (1.83) Cipolletti weirs have .25 H to 1 V side slopes, Z = 0.25. V … WebSimple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non …

Calculation of discharge over a broad-crested weir, Victor …

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 … WebSep 4, 2016 · The discharge equation for a broad crested weir is given as where Q = discharge over weir (m3/s, ft3/s) h = head (m, ft) L = crest length (m, ft) C = the flow coefficient that typically range between 2.4 and 3.087. The flow coefficient C can be obtained from the following figure. WebMar 5, 2024 · Plot a graph of Q (y-axis) against H 3/2 (x-axis) for the rectangular weir and Q against H 5/2 for the triangular weir.
