The opening to this weir is a 90 degree triangular notch. The bottom of the notch is the lowest point with the sides …
WebApr 12, 2024 · A triangular weir is preferred to a rectangular weir due to following reason. (1) The expression for discharge for a right angled V- notch or weir is very simple. (2) For measuring low discharge, a triangular weir gives more accurate results than a rectangular weir. (3) In case of triangular weir, only one reading, (H) is required for the ...
WebCalculate discharge (Q) and head (h) for each experiment, and record them in the Result Tables. For calculation purposes, the depth of the water above the weir is the difference between each water level reading and the datum reading, i.e., H = h-h o; Calculate H 5/2 and H 3/2 for the triangular and rectangular notches, respectively. WebThis calculates the flow rate over a Cipolletti weir, a commonly used weir in many irrigation districts. The weir opening has a flat, level bottom and the sides that have a particular slope. The water before the weir should be held in a relatively calm and smooth pool. There should be air (not trapped) underneath the water leaving the weir.
