The aim of that study was to evaluate the effect of compression on pressure drop in flexible, spiral wire helix core ducts used in residential and light commercial applications. Tests on ducts of 6, 8, 10 in. nominal diameters were conduted under different compression configurations following ANSI/ASHRAE standard 120-1999. That study suggests potential improvements to that standard and gives new data for duct design.
