Duct Fitting Loss Calculator May 2026

The diameter (round) or height and width (rectangular) of the duct.

By accurately sizing fans, you prevent over-pressurizing the system, which wastes energy.

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

Specifically identifying if it's a 90-degree elbow, a tee, or a reducing transition. Why You Should Use One The diameter (round) or height and width (rectangular)

I can help walk you through the calculation or direct you to a specific tool. Duct Pressure Loss Calculator | Plastec Ventilation

Common tools for this include digital apps from industry leaders like Price Industries or online calculators. If you can tell me: What is your airflow rate (CFM) and duct size

They calculate the pressure loss in inches of water gauge ("wg) or Pascals (Pa) for various round and rectangular fittings.
