How is the air volume of the fan calculated?

The definition of the air volume of the fan is: the product of the wind speed V and the cross-sectional area F of the air duct.

The definition of the air volume of the fan is:

The product of wind speed V and cross-sectional area F of the air duct.Since the wind speed can be accurately measured with a wind speed meter, the calculation of the air volume is also very simple for large fans, and the air volume can be calculated directly the formula Q = VF.

The number of fans to be determined needs to be based on the ventilation frequency of the selected room, to calculate the total air volume required for factory building, and then the number of fans can be calculated.

Calculation formula:

N = V × n/Q Where: N — Number of fans (units); — Site volume (m3);

n — Ventilation frequency (times/hour);

Q — Air volume of the selected fan model (m3/h)
