The flow rate of a fan can be calculated by multiplying the fan's air velocity (in feet per minute) by the area of the fan's outlet (in square feet). This will give you the volumetric flow rate in cubic feet per minute (CFM).
The parameters needed to calculate the flow rate of a fan include the fan's air velocity (in feet per minute) and the area of the fan's outlet (in square feet).
The air velocity of a fan can be measured using an anemometer, which is a device that measures air velocity. An anemometer can be placed in front of the fan's outlet to measure the air velocity in feet per minute.
Yes, the flow rate of a fan can be affected by other factors such as the size and shape of the fan's outlet, the fan's motor speed, and any obstructions in the fan's path.
The calculation of flow rate using parameters is generally accurate, but it may not take into account other factors that can affect the fan's performance. It is always best to measure the actual flow rate of a fan in real-world conditions for the most accurate results.
