Flexible ducting has been used for the
following example.
Example:
Exhaust connection, left . . . . . . . 4.9 m
Length (L) . . . . . . . . . . . . . . . . . . 1.2 m
Lower radius (R = 400 mm) . . . . 0.5 m
Height (H) . . . . . . . . . . . . . . . . . . 1.2 m
Upper radius (R) . . . . . . . . . . . . . 0.5 m
Wall pipe with louvred vent . . . . . 3.6 m
Effective duct length . . . . . . . . . 11.9 m
Result:
A duct diameter of 110 mm is adequ-
ate since the effective length is less
than 12 m as specified in Table II.
