The air delivery of a ventilating system may be
determined by:
1. Determine the equivalent duct length for each 90 degree
elbow by adding one foot of duct length for each inch of
duct diameter, i.e., a 4 inch diameter duct elbow equals
4 feet equivalent duct length and an 8 inch diameter duct
elbow equals 8 feet equivalent duct length.
2. Add the total straight length of duct and the equivalent
length for each elbow to obtain the total equivalent duct
length.
3. Locate the intersection of the fan performance curve and
the total equivalent duct length curves and draw a
vertical line down to the CFM scale and read the system
air performance.
(NOTE: 3
1
⁄ 4 " x 10" duct equals 6 inch diameter duct.)
