Blower RPM Formula
Blower RPM Formula if Pulley sizes are known: 〖RPM_a/〖DIA_b = 〖RPM〗_b/〖DIA〗_a
For Example:
Variables:
RPMa = Motor RPM 1750
RPMb = Blower Wheel RPM?
DIAb = Blower Pulley Size 16”
DIAa = Blower Motor Pulley Size 8”
Step 1: (1750 Motor RPM)/(16" Blower Pulley Diameter) = 〖RPM_b/(8” Motor Pulley Diameter)
Step 2: 1750 Motor RPM x 8" Motor Pulley Diameter = 〖RPM_b x 16" Blower Pulley Diameter
Step 3: (1750 Motor RPM x 8" Motor Pulley Diameter )/(16" Blower Pulley Diameter) = (〖RPM_b x 16" Blower Pulley Diameter)/(16" Blower Pulley Diameter)
Step 4: 14000/(16" Blower Pulley Diameter) = 〖RPM_b
Step 5: 〖RPM_b=875
