V Notch Weir Flow Calculator

Posted by Dinesh on

This calculator calculates the total discharge using coefficient of discharge, angle of the notch, height of the liquid above the apex of the notch values.

V Notch Weir Flow Calculation

°
mm
m3/s

Formula:

t = (8 / 15) × d × √ (2 × g) × tan(a / 2) × h(5 / 2)

Where,
t = Total Discharge
g = acceleration of gravity(9.81m/s²)
a = Angle of the notch
h = Height of the liquid above the apex of the notch(m)
d = Coefficient of discharge
