SUMMARY
The calculation of pressure thrust created by a fan involves understanding fan specifications such as size and CFM (Cubic Feet per Minute). To determine the pressure drop on the suction side of a cabinet fan, one can utilize a U-tube manometer filled with water to measure the vacuum in millimeters of water column. If static pressure data is unavailable, it is essential to convert CFM into FPM (Feet per Minute) using geometry, then apply Bernoulli's equation to convert velocity into velocity pressure, and finally convert that velocity pressure into force through further geometric calculations.
