Establish the number of elbows or bends necessary, noting the type of bend, angle and radius involved (see the "Additional duct lengths" table). Add the additional duct length (as derived by using the values specified in the "Additional duct lengths" table) to the actual duct length to get the effective length. [. . . ]
