This calculator calculates the friction loss using air volume flow, equivalent duct diameter, duct length values.

Air Duct Friction Loss Calculation

cfm
mm
mm
inches water
inches water per 100 feet

Formula:

Friction Loss = (0.109136 * q1.9 ) / (d5.02)
Friction Loss per 100 Feet = (0.109136 * q1.9 ) / (d5.02)*(l/100)

Where,
q = Air Volume Flow
d = Equivalent Duct Diameter
l = Duct Length
