Ducts are
normally circular in cross section;
however, in special circumstances, oval or rectangular ducts are
employed and these may be constructed of fiberglass, metal, or even
concrete. These ducts may be sized for preliminary approximations on
the basis of velocity. Table 18-5 provides calculated diameters
required for ventilation ducts at different quantities of airflow
for typical maximum design velocities. The nearest larger standard
sized ventilation duct (i.e. 18, 24, 36, 48, 60, 72 inches) may be
selected from the diameters shown in the tables for practical
application
