Flow Rate and Spray Angle

Droplet Size Basics

The spray pattern of a nozzle is made up of many droplets of varying sizes. Droplet size is the diameter of an individual spray droplet and measured in microns (micrometers) often notated with the symbol µ. One micron equals 0.001 mm(0.0000394″); there are 25,400 microns in one inch. For example, the diameter of a human hair is about 100 microns.

Main Factors Affecting Spray

All the data relating to our nozzles contained in our catalog are based on spraying water at standard temperatures. When spraying liquids other than water, performance is likely to be different. The following presentation describes how various liquid properties and operating conditions affect performance.
