Web for instance, if the longest duct (from the blower to the farthest vent) is 30 ft, a 6″ duct carrying 200 cfm will result in a friction loss of 30 ÷ 100 x 0.3 = 0.09 in.wg. 10 ach, or every 6 minutes. A 4 x 10 duct rates around 150 cfm. Furthermore, these include flow of air volume, which dictates the amount of air needed to maintain comfort conditions within the space, as well as air velocity, which influences the.
