WebAir flow is the quantity of air moving and is expressed in CFM. Air velocity is the actual speed of the air (independent of how much air is being moved) and is expressed in FPM. Area. To convert between velocity and flow rate, the cross-sectional area of the air duct is required, which are generally either rectangluar or circular. WebPer the Copper Tube Handbook ( www.copper.org ), once the fluid temperature exceeds 140°F, the velocity needs to slow down to 2 to 3 fps, as the water becomes more aggressive the hotter it becomes. To slow the velocity of water in a given pipe, either (a) the flow rate must reduce or (b) the pipe must get larger. The values in the UPC are ...
