General
“Cubic Feet Per Minute” K Factors
NOTE: For the appropriate sensor “K” factor:
• For VAV controllers needing K
CFM
for setup, see
the formulas under “Cubic Feet Per Minute” K
Factors on page 2.
• For VAV controllers needing K
FPM
for setup, see
the formulas “Feet Per Minute” K Factors on
page 3.
For K
FPM
, see “Feet Per Minute” K Factors on page
3.
For rectangular ducts, K
CFM
= K

(with duct cross-section measurements in inches).
For round ducts, K
CFM
= K
FPM
x (πr

/144) (with duct
cross-section measurements in inches).
NOTE: To conveniently determine the radius
of an installed round duct, measure
the circumference with a string and
tape measure and calculate radius =
circumference/2π. The K
CFM
values for the
most common (diameter) sizes of round
ducts are listed above. (Diameter = 2r.)
