Chemical Metering Pump Feed Rate Calculations
GPH = | GPM x .006 x PPM |
% Conc. X S.G. |
LPH = | M³/h x mg/l x 0.1 |
% Conc. X S.G. |
Metric | English | |
---|---|---|
m³/h | GPM = | Flow to be treated |
0.1 | .006 = | Constant |
mg/l | PPM = | Dosage required |
% Conc. | % Conc. = | Concentration of chemical in pumped solution- Use full number (15% solution is [15] in formula not (.15)) |
S.G. | S.G. = | Specific gravity at pumped solution |
Useful Equivalents | |
---|---|
GPM x 1440 = GPD | GPD x 6.944 x 10⁴ = GPM |
liter x 1.0 x 10³ = cm³ | Gal. (H²O) x 8.337 = pound (H²O) |
GPM x 227.1 = l/h | l/h x 4.403 x 10³ – GPM |
l/m x 5.886 x 10⁴ = ft³/sec. | GPM x 2.228 x 10³ = ft³/sec. |
Gal. x 3.785 = liter | liter x 2.642 x 10¹ = Gal |
