Water vs Chemical Solution: Why Can Spray Nozzle Flow Differ ?
Using the same spray nozzle at the same pressure does not always mean you will get the same flow rate.
When switching from water to a chemical solution, changes in liquid properties can affect nozzle performance.
πΉ Specific Gravity
A higher specific gravity means a denser liquid. At the same pressure, this generally results in a lower flow rate through the nozzle.
πΉ Viscosity
Higher-viscosity liquids can affect flow resistance and spray formation.
Depending on the nozzle design and operating conditions, this can influence flow rate, spray angle, droplet size, and atomization.
πΉ Surface Tension
Changes in surface tension can influence droplet formation, spray breakup, and wetting characteristics.
πΉ Chemical Concentration
Changing the concentration of a chemical solution can alter properties such as specific gravity and viscosity, causing nozzle performance to differ from water-based specifications.
The Simplified Relationship :
Q β β(ΞP / Specific Gravity)
Where Q is flow rate and ΞP is the pressure drop across the nozzle.
Q β β(ΞP / Specific Gravity)
Where Q is flow rate and ΞP is the pressure drop across the nozzle.
This is why water-based nozzle flow charts should be treated as a reference, especially when the actual application uses a different liquid.
For critical applications, consider the actual liquid properties, operating pressure, temperature, required flow rate, and spray pattern when selecting a nozzle.
π‘ The nozzle may be the sameβbut the liquid is not.
