Enter the values of Volumetric Flow Rate of the air from the duct CFM_{(Ft}^{3}_{/minute)} & Cross-sectional Area A_{(Feet}^{2}_{)} to determine the value of Duct Velocity V_{(FPM)} .

__Duct Velocity Formula:__

__Duct Velocity Formula:__

The Duct Velocity V_{(FPM)} in Feet Per Minute is equal to the Volumetric Flow Rate of the air from the duct CFM_{(Ft}^{3}_{/minute)} in Feet cubic per minute is divided by the Cross-sectional Area A_{(Feet}^{2}_{)} in feet square.

The Formula of Duct Velocity can be writtern as,

V_{(FPM)} = CFM_{(Ft}^{3}_{/minute)} / A_{(Feet}^{2}_{)}

Here,

V_{(FPM)} = Duct Velocity in Feet Per Minute

CFM_{(Ft}^{3}_{/minute)} = Volumetric Flow Rate of the air from the duct in Feet cubic per minute

A_{(Feet}^{2}_{)} = Cross-sectional Area in feet square

__Calculation for Duct Velocity:__

__Calculation for Duct Velocity:__

1)Determine the Duct Velocity and given for Volumetric Flow Rate = 1,000 ft^{3}/min , Cross-sectional Area = 5 ft^{2}.

Solution

V = CFM / A

V = 1000 / 5

V = 200FPM.

2)Determine the Cross-sectional Area and given for Volumetric Flow Rate = 1,000 ft^{3}/min , Duct Velocity = 200FPM.

Solution

V = CFM / A

200 = 1000 / A

A = 5ft^{2}.
