Qt = Total air flow of Dust collector. Q1 = Air Flow in first area. Q2 = Air Flow in second area. etc. Static Pressure is a loss due to the air flow pressure pickup area to exit the dust collector system.The pressure loss can occur in the suction, ducting, elbow and cyclone. Calculation of static pressure is based on the duct size.t = Total air flow of Dust collector. Q1 = Air Flow in first area. Q2 = Air Flow in second area. etc. Static Pressure is a loss due to the air flow pressure pickup area to exit the dust collector system.
