Duct Fitting Loss Calculator -

Helps ensure that the total pressure does not exceed the capacity of the air handling unit (AHU).

By calculating both straight duct friction loss and fitting loss, they provide the total static pressure needed for proper duct design. Key Data Used in Calculations duct fitting loss calculator

The volume of air (CFM or L/s) passing through the fitting. Helps ensure that the total pressure does not

The diameter (round) or height and width (rectangular) of the duct. allowing for easier total pressure calculations.

The calculator converts the resistance of a fitting into an equivalent length of straight duct, allowing for easier total pressure calculations.
