Flow equation parameters -B1
Units Used For Flow Parameters in Equation C F M
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=lPrBI-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=fan pressure,RP= room pressure
