Face Velocity Calculator, Formula, Face Velocity Calculation

Face Velocity Formula:

Enter the values of Air Flow Rate AF_(ft³_/s) & Face Area FA_(ft²₎ to determine the value of Face Velocity FV_(ft/s) .

Face Velocity Calculator:

The Air Flow Rate AF_(ft³_/s) in feet cubic per second is divided by the Face Area FA_(ft²₎ in feet square is equal to the Face Velocity FV_(ft/s) in feet per second.

The Formula of Face Velocity can be writtern as,

FV_(ft/s) = AF_(ft³_/s) / FA_(ft²₎

Here,

FV_(ft/s) = Face Velocity in feet per second

AF_(ft³_/s) = Air Flow Rate in feet cubic per second

FA_(ft²₎ = Face Area in feet square

Calculation for Face Velocity:

1)Calculate the Face Velocity and given for Air Flow Rate 8075 ft³/s , Face Area = 5 ft².

Solution

FV = AF / FA

FV = 80 / 5

FV = 16ft/s.

2)Calculate the Face Area and given for Air Flow Rate 8075 ft³/s , Face Velocity = 16ft/s.

Solution

FV = AF / FA

16 = 80 / FA

FA = 5 ft².
