The V-shaped weir is called as V-Notch or triangular weir. The flow rate is defined as the amount of fluid that passes through a channel per unit time. This page shows you the triangular weir formula which is a simple formula that helps you to determine the flow rate of a v-shaped weir. Just substitute the height of the weir in the V-Notch weir flow formula and do the demanding operations to get the flow rate. Be conscious about the unit of input you use in the formula.

Where,

h = Height (ft)

q = Flow Rate

The above Triangular weir formula in this page uses the multiplication factor of 2.49 to determine the flow rate using height measurement in simple.
