Which two factors can you change to adjust nozzle flow rate?

• A. Pressure and/or Nozzles
• B. Temperature and Humidity
• C. Viscosity and pH
• D. Speed and Weight

Answer: (A)

The main way to change how much liquid comes out of the nozzle is by adjusting the pressure and by changing the nozzle itself (its size or design). Flow rate through a nozzle depends on how hard you push the liquid and how large the orifice is. Higher pressure pushes more liquid per unit time, and a nozzle with a larger or differently shaped orifice can produce more flow or a different spray pattern at the same pressure. Temperature and humidity don’t directly set the nozzle’s flow rate; they can affect spray characteristics like drift and evaporation, but not the amount of liquid exiting the nozzle in a given moment. Viscosity and pH can influence flow somewhat, but the most reliable, controllable factors you adjust in practice are pressure and the nozzle. Speed and weight don’t determine the nozzle’s flow rate.
