Triangular weir formula
WebTriangular weirs are sharp crested thin plates with V-shaped opening (or notch). These plates are installed at the exit of a channel, tank, or basin in order to measure the real-time flow of water. For a given weir profile size … WebThe Discharge over triangular notch or weir formula is known from the relation considering the coefficient of discharge, head of the liquid, and angle of the notch is calculated using Theoretical Discharge = (8/15)* Coefficient of Discharge *(tan (Angle A /2))* sqrt (2* [g])*(Head of the liquid ^2.5).To calculate Discharge over Triangular Notch or Weir, you …

The formula for calculating weir discharge: Q = CLH 1.5. Where: Q = Weir Discharge. C = Co-efficient of Weir. L = Length of the Weir.
WebFeb 21, 2024 · The coefficient of discharge for triangular side weir was calculated using Rehbock empirical equation for two different models installed with and opposite flow direction. The ANN was constructed from (156) data with three layers: eight input layer, ten hidden layer and one output layer, with (MSE = 0.00113) and ( R = 0.982) and the … WebAug 25, 2024 · Advantages of Triangular Notch or Weir: A triangular notch or weir is preferred to a rectangular weir or notch due to following reasons: 1. The expression for discharge for a right – angled V-notch or weir is very simple. 2. For measuring low discharge, a triangular notch gives more accurate results than a rectangular. 3.
WebOct 1, 2024 · A V-notch weir is also called the triangular notch or weir. The discharge over a triangular weir or notch is given by the: Q = 8 15 C d t a n θ 2 2 g H 5 / 2. Where, Q = discharge of fluid, C d = Coefficient of discharge, θ = Notch angle and H = height of water above the notch. From the equation we can see that Q is proportional to H5/2. WebWeirs are constructed as an obstruction to flow of water. These are commonly used to measure the volumetric rate of water flow in order to prevent flooding and make rivers navigable.
