What is the relationship between the air volume of Roots blower and the air pressure?

The pressure of Roots blower has nothing to do with the air volume, and the selection pressure of the blower cannot increase the air volume of the blower. The air volume of Roots blower is closely related to the rotation speed, and the higher the rotation speed of the blower, the greater the air volume.

Generally, the air volume and pressure of the cooling fan are the air volume (* * air volume) when there is no pressure difference between the air inlet and outlet of the fan, and the pressure difference (* * static pressure) between the air chamber and the outside air when the air volume of the fan in the closed room is zero.

They are not two isolated performance indicators, but they restrict each other. The relationship between velocity and pressure in fluid mechanics is that the pressure difference between air flows decreases.
