WebSome are made specifically for air velocity measurement and are calibrated directly in feet per minute. They are correct for standard air conditions, i.e., air density of .075 lbs. per cubic foot which corresponds to dry air at 70°F, barometric pressure of 29.92 inches Hg. To correct the velocity reading for other than standard air conditions ... WebOct 1, 2024 · FIGURE 3. Flow-vs.-power curve. Generally, the power required by a fan increases as flow through the fan increases. With many airfoil and backward-curved or backward-inclined fans, however, power reaches a peak value and then decreases as flow increases. 2 This type of power curve is known as “non-overloading.”.

WebAir Velocity is measurement of the rate of displacement of air or gas at a specific location. Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time.
