Procedure
Sample calculation
1.
Measure the length needed for the straight sections of ducting.
Multiply this value by the corresponding relative pipe length
from table I.
2.
Calculate the number of bends and components needed. Use
Table I to help you add together their relative pipe lengths.
3.
Add together all of the relative pipe lengths calculated above in
order to calculate the total ducting length.
4.
Refer to Table II for the pipe diameter needed for the total duct-
ing length.
Table I
