WebbSharp-crested gates, commonly referred to as notches, exist manufactured from sharp-edged thin plates. This your between the flow rate and water depth above the weir can be derived by applying the Bernoulli’s equation furthermore by making some assumptions with regard at print loss and pressure marketing about the flow passing over the weir. Webb4 aug. 2024 · If 2b is less than H, the weir is called a narrow-crested weir. Broad-Crested Weir Formula. If a broad crested weir has the minimum height needed for critical flow, then the simple equation, Q = 1.6 L H3/2, can be used for flow rate calculations over that broad crested weir. What Does a Weir Do?
WebbL = combined length of the horizontal portions of the weir in ft. h2 = head above the horizontal crest in ft. When h 1 is 1 ft or less, the flow is confined to only the V-notch … WebbThe Kindsvater-Carter rectangular weir equation (ISO, 1980): The sum b+K b is called "effective width" and the sum h+K h is called "effective head." The value for g is 9.8066 m/s 2 and K h =0.001 m. C e is a function of b/B and h/P, and K b is a function of b/B.
