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.
🔹 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.
🔹 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.
🔹 Surface Tension
Changes in surface tension can influence droplet formation, spray breakup, and wetting characteristics.
🔹 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 ∝ √(ΔP / Specific Gravity)
Where Q is flow rate and ΔP is the pressure drop across the nozzle.
Q ∝ √(ΔP / Specific Gravity)
Where Q is flow rate and ΔP 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.
💡 The nozzle may be the same—but the liquid is not.
