WebDec 22, 2024 · The flow rate formula, in general, is Q=Av Q = Av where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point. In some situations, such as that of water flowing in a riverbed, calculating A is difficult, and the best you can do is an approximation. WebNov 22, 2024 · This is the formula used for Filtration Rates: F R = Flow SurfaceArea Since Filtration Rates are expressed as gpm/ft 2 then it only makes sense to convert the flow rate to gpm prior to dividing by the filter surface area. However, in this equation it is not necessary to do so prior to dividing. The “Pie-Wheel” for Filtration Rates looks like this:
