Most air flow measuring devices indicate air velocity not as a volume
flow. To convert air flow from a velocity to a volume rate, perform the
following steps:
1. Calculate the cross-sectional area of the exhaust duct in meters
(feet).
A = (3.1415) (r
2
)
A = Cross-sectional area of the exhaust duct
r = radius of the exhaust duct in meters (feet)

A = (3.1415)(0.1111)
A = 0.349
2. Calculate the volume flow rate in cmm (cfm).
volume flow rate = velocity x cross-sectional area
