The weir equation
WebThe flow rate measurement in a rectangular weir is based on the Bernoulli Equation principles and can be expressed as: q = 2/3 cd b (2 g)1/2 h3/2 (1) where q = flow rate … WebThe equation recommended by the Bureau of Reclamation in their Water Measurement Manual, for use with a suppressed rectangular weir is: Q = 3.33 B H 3/2, where Q is the water flow rate in ft 3 /sec, B is the length of the weir (and the channel width) in ft, and H is the head over the weir in ft.
