SCFH – Standard Cu. Ft. Per Hour SLPM – Standard Liters Per Minute The Metal Orifice Air Flow data obtained with Type B restrictor. Flow rates for other metal restrictors are essentially the same as for Type B. The Metal Orifice Air Flow data supercedes previous publications. |
Water Flow Notes |
N/A The Metal Orifice Water Flow data calculated based on the Cv for each orifice. Flow = Cv √ΔP. ΔP = differential pressure in psid. It is assumed that the region on either side of the orifice is fully flooded with no air pockets. |
