Water Velocity Calculator, Formula, Water Velocity Calculation

Water Velocity Calculator:

Enter the values of Volumetric Water Flow Rate WFR_(ft³_/s) & Cross-sectional Area A_(ft²₎ to determine the value of Water Velocity Vw_(ft/s) .

Water Velocity Formula:

The Water Velocity Vw_(ft/s) in feet per second is equal to the Volumetric Water Flow Rate WFR_(ft³_/s) in feet cube per second is divided by the Cross-sectional Area A_(ft²₎ in feet square.

The Equation of Water Velocity can be writtern as,

Vw_(ft/s) = WFR_(ft³_/s) / A_(ft²₎

Here,

Vw_(ft/s) = Water Velocity in feet per second

WFR_(ft³_/s) = Volumetric Water Flow Rate in feet cube per second

A_(ft²₎ = Cross-sectional Area in feet square

Calculation for Water Velocity:

1)Determine the Water Velocity and given for Water Flow Rate = 200 ft²/s , Cross-sectional Area = 20 ft².

Answer

Vw = WFR / A

Vw = 200 / 20

Vw = 10feet/second.

2)Determine the Cross-sectional Area and given for Water Flow Rate = 200 ft²/s , Water Velocity = 10feet/second.

Answer

Vw = WFR / A

10 = 200 / A

A = 20 ft².
