help with dryer. vent size problem?
Reducers, elbows, tees, etc., have an equivalent duct length [of 4" duct or 3" duct] but I cannot find the reducer value anywhere on the Web.
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.
