  Leonhard Euler (1707-1783) was a pioneering Swiss mathematician and physicist.
  
  ## Overview
  
  A triangular notch is also called a V-notch. Consider a triangular notch, in one side of the tank, over which water is flowing as shown in figure.
  
  Let,
  • H = Height of the liquid above the apex of the notch
  • θ = Angle of the notch
  • Cd = Coefficient of discharge
  
  From the geometry of the figure, we find that the width of the notch at the water surface,
  
  Area of the strip =
  
  We know that the theoretical velocity of water through the strip =
  
  and discharge over the notch,
  
  The total discharge over the whole notch may be found out only by integrating the above equation within the limits 0 and H.
  
  A triangular notch gives more accurate results for low discharges than rectangular notch and the same triangular notch can measure a wide range of flows accurately.

  ##### Example - Discharge through a triangular notch
  Problem
  A right-angled V-notch was used to measure the discharge of a centrifugal pump. If the depth of water at V-notch is 200mm, calculate the discharge over the notch in liters per minute. Assume coefficient of discharge as 0.62.
