There are options to input the existing duct dimensions and one of either the airflow or velocity values to derive the calculated duct friction loss.In the Range of Duct Sizes mode, you can specify minimum and maximum friction loss and airflow values to display a range of duct sizes that fall in between the friction loss bounds.You can specify additional parameters such as the duct shape (rectangular, round, or oval), the air temperature and the air pressure. The results include both the exact and rounded height and width (or diameter) dimensions and the calculated velocity and friction loss.In the Size by Dimensions mode, you can analyze an existing duct system.

In the Size by Airflow mode, you can specify the total airflow in CFM (or Ls), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). Think of this application as a digital version of the classic Trane Ductulator. JoeThe Duct Sizer application allows you to quickly size one HVAC duct run or a range of duct sizes using the constant friction method.
