Duct Fitting Loss Calculator Apr 2026

The volume of air (CFM or L/s) passing through the fitting.

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

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 The volume of air (CFM or L/s) passing through the fitting

you are calculating (e.g., radius elbow, mitered bend, reducer)? What is your airflow rate (CFM) and duct size ? duct fitting loss calculator
