Air flow in HVAC ducting can be calculated using the formula Q = AV

• Q = air flow rate in cubic feet per minute (CFM)

• A = cross-sectional area of the duct in square feet

• V = air velocity in feet per minute (FPM)

• Air velocity can be measured using a pitot tube or an anemometer

• Duct sizing and layout can affect air flow and should be considered in calculations
