*To find centipoises, multiply centistokes by specific gravity.

To find the flow rate for liquids other than water, determine the flow rate for water and divide by the viscosity (in centipoises) of the desired liquid. Example: For a medium bronze filter at 5 inches of water pressure, the flow of water is 0.53 gpm/sq. in., then for the flow of kerosene (viscosity 2.35 centipoise at 70° F.) at 5 inches of water pressure, the flow is 0.53 ÷ 2.35 = 0.22 gpm/sq. in.
