Once you have completed your and installation, here is how to perform a basic calculation:
The software uses the Darcy-Weisbach equation and Moody chart approximations. You input the air volume (CFM/m³/s) and desired friction rate (typically 0.05 to 0.15 in. wg/100 ft). The software outputs: Design Tools Duct Sizer Version 6.4 Free Download
, the software is still widely available through their official digital resource portals. Download and Installation Overview Official Source : The software is part of the Daikin Design Software : It typically downloads as a self-extracting zip file. : After unzipping, look for an executable file (often named DuctSizer.exe ) to launch the application.

At its core, Duct Sizer Version 6.4 is built to solve the complex aerodynamic equations required to move air effectively through a network of ducts. The software typically utilizes the equal friction method, the velocity reduction method, or the static regain method to calculate dimensions based on user-defined inputs. Designers input critical parameters such as the required airflow rate in cubic feet per minute or liters per second, the desired air velocity, and the allowable friction loss per unit length. The software then instantly computes the required diameter for round ducts or the equivalent dimensions for rectangular and oval ducts. This automation drastically reduces the margin of human error associated with manual look-up tables and speeds up the drafting and design phases of a project.
