3. Calculation example
A Wall pipe, with louvred vent
= 1 x 3.8 m Additional duct
length
= 3.8 m
B/D 2 Elbows, 90°
= 2 x 0.8 m Additional duct
length
= 1.6 m
C 0.5 m plastic piping
= 0.5 x 1 m Additional duct
length
= 0.5 m
E Side connection, left
= 1 m Additional duct length = 1.0 m
Effective duct length = 6.9 m
Result: A duct diameter of 100 mm is
adequate as the effective duct length is
less than the 20 m specified in Table II.
