Flow at 20 psi
WebAir 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. Volume flow is usually measured in Cubic Feet per Minute (CFM).

WebMar 29, 2024 · To calculate GPM from PSI, use this formula: \text {GPM} = \frac {500 \times \text {PSI}} {\text {operating pressure}} For example, if your pressure was 100 PSI and you want to know how many gallons of water will come out per minute, you would divide the 500 by 100 to get 5. To put it another way: 5 gallons of water flow out every 1 minute when ...
