Coefficient of Velocity Calculator:

Enter the values of Horizondal distance x_(ft), Vertical Distance y_(ft) & Head of Water h_(ft)   to determine the value of Coefficient of Velocity Cv_(m/s).

Coefficient of Velocity Formula:

The Coefficient of Velocity Cv_(m/s) in meter per second is equal to the SQRT of the Horizondal distance x_(ft) in feet is squared is Divided by the value of 4 into multiply the Vertical Distance y_(ft) in feet and again multiply the Head of Water h_(ft) in feet.

The Formula of Coefficient of Velocity can be writtern as,

Cv_(m/s) = SQRT ( x²_(ft) / ( 4 * y_(ft) * h_(ft) ) )

Here,

Cv_(m/s) = Coefficient of Velocity in meter per second

x_(ft) = Horizondal distance in feet

y_(ft) = Vertical Distance in feet

h_(ft) = Head of Water in feet

Coefficient of Velocity Calculation :

1)Determine the Coefficient of Velocity and given for Horizondal distance = 4ft , Vertical Distance = 3ft , Head of Water = 5ft.

Answer

Cv = √( x² / ( 4 * y * h ) )

Cv = √ ( 4² / ( 4 * 3 * 5 ) )

Cv = 0.516m/s.

2)Determine the Head of Water and given for Horizondal distance = 4ft , Vertical Distance = 3ft , Coefficient of Velocity = 0.516m/s.

Answer

Cv = √( x² / ( 4 * y * h ) )

0.516 = √ ( 4² / ( 4 * 3 * h ) )

h = 5ft.
