What is broad-crested weir?

Broad crested weirs are robust structures that are generally constructed from reinforced concrete and which usually span the full width of the channel. They are used to measure the discharge of rivers and are much more suited for this purpose than the relatively flimsy sharp-crested weirs.

What is velocity of approach?

The velocity of approach or separation is defined as the rate of change of relative displacement between two bodies. The velocity of approach is defined when the displacement between the bodies is decreasing and separation when the displacement between the bodies is increasing.

FAQ

What is Discharge over a broad-crested weir with velocity approach?
The Discharge over a broad-crested weir with velocity approach is known while considering the head of liquid and head due to Va, coefficient of discharge, and length and is represented as Q=1.705*Cd*l*(((H+h a)^1.5)-((h a)^1.5)) or Discharge=1.705*coefficient of discharging*Length*(((head of the liquid+head due to Va)^1.5)-((head due to Va)^1.5)). The coefficient of discharging or efflux coefficient is the ratio of the actual discharge to the theoretical discharge, Length is the measurement or extent of something from end to end, The head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container and The head due to Va is considered as the elevation difference between the two circled points on the surface of the approach flow.
How to calculate Discharge over a broad-crested weir with velocity approach?
