Full Description

Specific conclusions are: 1. Joint size and joint spacing affect the pressure drop for an air flow in a duct. 2. Beaded construction and cross breaks, both common with rectangular ducts, also contribute to the pressure drop for air flow in a rectangular duct, but, comparatively, these effects are not as strong as those due to the joints. 3. For the range of test covered in this work, no significant effect of aspect ratio was found when correlating the data for the "smooth" passages with the parameters of the Moody diagram using the hydraulic diameter.
