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.
