Rectangular To Circular Duct

The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe.

Rectangular to circular duct.

The table is based on the ducts friction loss formula. The rectangular dimensions and the air flow volume are adapted to the equal friction loss. The equivalent diameter is the diameter of a circular duct or pipe that for equal flow gives the same pressure loss or resistance as an equivalent rectangular duct or pipe. Sound costs maximum airflow and more.

Round ducts have virtually no wall deflection in normal operating conditions and the helical spiral seams strengthen the duct even more. Spiral ducts are normally produced in longer lengths than rectangular ducts. Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint. As a result spiral duct systems usually weigh 30 less than equivalent rectangular duct systems less material.
