12.1 General information about nozzles
Each nozzle type has a different volume flow, spray pattern, drop size and nozzle
characteristics. The liquid to be sprayed, the environmental conditions, the nozzle
characteristics and official regulations such as distance conditions, drift reduction
classes etc. must be taken into account for the selection of the nozzles.
The volume flow of a nozzle changes with the spraying pressure. If the volume
flow of a nozzle (l/min) is doubled, four times the spraying pressure (bar) is requi-
red.
