Formulas for CSC-2000, CSC-3000, and CSP-4000 Series
For Flow For Volume
DP = (FPM/K)
2
FPM = K x SQRT(DP)
CFM
K x Area
CFM =
K x SQRT(DP) x Area
Feet Per Minute in a VAV box equals the (relevant model’s) K factor
times the square root of the differential pressure (in “wc”).
Cubic Feet per Minute in a VAV box equals the relevant sensor
model’s K factor times the square root of the differential pressure (in
“wc”) times the cross-section area (in square feet).
NOTE: These formulas are for CSC-2000 series, CSC-3000 series, and CSP-4000 series controllers with built-in “differential pressure”
sensors
. CEP-4000, CSP-5000, KMD-7000, and BAC-7000 operate differently—see their respective installation guides and application
guides for more information.
NOTE: CFM (cubic feet per minute) = FPM (feet per minute) times the duct cross-section area (in square feet).
