Units Used For Flow Parameters in Equation CFM
Fan pressure (FP) is the measured fan pressure when using a self-referenced fan or when the room pressure is
negative. lf using a fan which is not self-referenced, and the room pressure is positive, fan pressure is calculated
by subtracting the measured room pressure from the absolute value of the fan pressure.
lf PrA is greater than 0 or fan is self-referencing: FP = lPrBl - PrA
lf PrA is less than 0 or fan is self-referencing: FP = PrB
Flow calculations are not valid if fan pressure is less than either MF or (K2 x lRPl)
FP = fan re, RP = room re
