Cfm Duct Sizing Chart Description

Sizing and Balancing Air Duct Systems

to size a duct, only the flow rate of the Figure 1 the duct section and identify that line on the chart. The duct diameter should then be selected so that the flow rate, the eco­ nomic factor and the diameter line intersect. For example, ifa duct with allow rate ofO. I 013/s (213 cfm) is sized using the new chiut, the size would be 180 mm (7 .1 in.), 150 mm (5.9 in.), and 100 mm (3.9 in
