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:__

__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 ( x^{2}_{(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 = √( x^{2} / ( 4 * y * h ) )

Cv = √ ( 4^{2} / ( 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 = √( x^{2} / ( 4 * y * h ) )

0.516 = √ ( 4^{2} / ( 4 * 3 * h ) )

h = 5ft.
