Duct Fitting Loss Calculator -

A duct fitting loss calculator is an essential HVAC tool used to determine the pressure drop (resistance) caused by fittings like elbows, tees, transitions, and takeoffs within a duct system. These tools help calculate the total static pressure a fan must overcome to deliver the necessary air volume. Key Functions of a Duct Fitting Calculator

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

Common tools for this include digital apps from industry leaders like Price Industries or online calculators. If you can tell me: A duct fitting loss calculator is an essential

The diameter (round) or height and width (rectangular) of the duct. What is your airflow rate (CFM) and duct size

Proper sizing prevents noisy systems and ensures adequate air delivery to rooms.

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

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