Coefficient of Velocity Formula
The following equation is used to calculate the Coefficient of Velocity.
Cv = SQRT (x^2 / (4*y*h) )
- Where Cv is the coefficient of velocity
- x is the horizontal distance
- y is the vertical distance
- h is the head of water
How to Calculate Coefficient of Velocity?
Example Problem:
The following example outlines the steps and information needed to calculate Coefficient of Velocity.
First, determine the horizontal distance . In this example, the horizontal distance is found to be 3ft.
Next, determine the vertical distance . For this problem, the vertical distance is found to be 2ft.
Next, determine the head of water . In this case, the head of water is measured to be 4ft.
Finally, calculate the Coefficient of Velocity using the formula above:
Cv = SQRT (x^2 / (4*y*h) )
Cv = SQRT (3^2 / (4*2*4) )
Cv = .530
