A 5% solution requires different dosing than a 10% solution of the same chemical.<\/li>\n<li><strong>System Volume:<\/strong> The total liquid volume being treated determines the chemical amount needed per cycle. Treating a 10,000-liter tank differs from treating 100,000 liters.<\/li>\n<li><strong>System Pressure:<\/strong> Higher pressures reduce actual pump output. Pump performance curves show how pressure affects delivery rate\u2014critical for calculating real-world performance.<\/li>\n<li><strong>Fluid Properties:<\/strong> Viscosity, density, and chemical compatibility affect flow rate. Thicker liquids move slower through the same pump than thin liquids.<\/li>\n<li><strong>Desired Dosing Frequency:<\/strong> Continuous dosing requires different flow rates than intermittent dosing. A system dosed 24\/7 needs lower per-cycle rates than one dosed 2 hours daily.<\/li>\n<li><strong>Feed Tank Height and Suction Conditions:<\/strong> Suction lift above the pump inlet reduces pump capacity.
