# Ductulator duct sizing calculator book

The Ductulator Duct Sizing Calculator is a hand held rotating calculator used for sizing supply and return duct systems using the equal friction design method. Includes scales for friction loss per unit length, air volume, air velocity, round duct diameter, and rectangular duct diameters.

Online Ductulator Free Duct Size Calculator. Ductulator calculats duct dimensions using equal friction method or velocity method. It calculates both rectangular and round duct dimensions. And it shows the velocity andor static pressure loss of air for both types of duct shape. It works with IP units (United States, United Kingdom) and Ductulator trane Duct Sizing Calculator, English& Metric Units.
