Bazins Weir Flow Calculation
The calculator will calculate the water flow rate in horizontal open channels, rivers and sewage plants for given values.
Determine the water flow rate in horizontal open channels, rivers and sewage plants based on the values of discharge constant, width of the weir and head on the weir using the Bazin's formula.
q = 0.66 × Cd × b × (2g)0.66 × h1.5
q = Water Flow Rate
Cd = Discharge Constant
b = Width of the Weir
g = Gravity (9.81 m/s²)
h = Head on the Weir
Types of Weirs
1. Based on Shape of the Opening.
2. Based on Shape of the Crest.
Broad- crested weir.
3. Based on Effect of the sides on the emerging nappe.
