Static Pressure Change Formula based on RPM Change
Blower RPM Change Static Pressure Effect:
Static Pressure 2=Static Pressure 1 x (RPM2/RPM1)^2
For Example:
Original RPM 1 = 100.
Static Pressure 1 = 1.25”.
New RPM 2 = 125.
Step 1: Static Pressure 2= 1.25" x [125/100]^2
Step 2: Static Pressure 2= 1.25" x [1.25]^2
Step 3: Static Pressure 2= 1.25" x 1.5625
Step 4: Static Pressure 2= 1.95" W.C.
