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. If 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.
If PrA is greater than 0 or fan is self -referencing: FP = jPrBj - PrA
If 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 IRPI)
FP = tan pressure, RP = room pressure
