|Cv || = ||Flow Coefficient = Q * √ΔP/G|
|Q || = ||Flow rate in GPM of water|
|ΔP || = ||Pressure Drop = G * (Cv/Q)2|
|G || = ||Specific gravity|
Cv is the fluid flow through a piping component at 60oF in US GPM at a pressure drop of 1 PSI.
If Cv is > Q, the pressure drop is < 1 PSI.
Formulas and results are based on perfect flow conditions; results will vary in actual practice
if there is any flow turbulence, temperature variations, pressure shock waves, and as the
filter accumulates debris.
