Flow Advisor - Weir Flow Calculations

Flow from Weirs

Flow from Weirs may be used to estimate the water flow rate discharged. The calculations can be performed on different types of weir:

Rectangular weir with end contractions.
Trapezoidal weir with sloping end contactions.
Triangular weir with end contractions.
Smooth channel (horizontal) without contactions.

Weir Calculations

Each design needs a different calculation method to estimate the flow rate.
All four calculations methods use the weir dimensions, the water head (raised to some power - different for each design), and a constant factor (again different for each design.)
Each type of 'Weir' has an appropriate calculation screen.
Select a calculation screen by choosing a weir type.
Enter the data for your application.
Click the 'Calculate button'.
