QUICK-GUIDE
-
Select the duct material from the drop-down list (most duct sizing tools are typically based on galvanised steel ducting by default)
-
Enter the air flowrate in litres/second (can change to cubic metres/second by use of drop-down to the right of the input)
-
Enter an internal duct size (this must be limited to a maximum aspect ratio of 5:1 for the results to be valid)
-
The resulting velocity and pressure drop per unit length are displayed in the blue box.
