NOZZLES AND SYSTEMS FOR MORE INTELLIGENT SPRAY SOLUTIONS


   The volume of a large droplet corresponds to the volume of 8 droplets of half the diameter.
The surface of the large droplet is four times as big as the one of a small droplet. The total surface of the 8 small droplets, however, is twice as big as the surface of a large droplet
