Misting Nozzle Plume is a function of nozzle orifice size, nozzle spray angle and pressure. Maximum nozzle pressure is 1000 psi, minimum pressure is 100 psi. We will walk through the variations.
Orifice Size and Connection Type
This is a good place to go through the nozzle variations of orifice size and connection type. There is a range of misting nozzle orifice diameters from 0.10mm through 1.0mm. There is actually a 0.08mm but it is so close to the 0.10mm it's hard to tell the difference as far as plume size is concerned.
Orifice sizes are, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50, 0.60, 0.80, and 1.0. All in mm (millimeter) dimensions.
There are 4 basic connection types. This is the thread type that connects to the tube fitting. We have 10/24unc (most common), 12/24unc, 1/8in NPT, and a 1/4in Slip-Lock connection type.
Back to nozzle plume. There is a plume spray angle that is associated with each nozzle. It ranges from 30 degrees to 80 degrees approximately. The 30 spray has no defined angle to it as seen in the smaller orifice sizes, 0.08 - 0.15mm. You start to get some definition to the spray angle in the form of a cone shape with the larger orifice sizes, 0.20mm and above. Spray angle may not be the same on every nozzle of the same orifice size. Manufacturing is difficult and there are other factors internal to the nozzle that can very spray angle a small amount.
Water pressure will play a large part in plume size. The more pressure the greater amount of water. However, when spray is pointed down the width or diameter of the plume does not necessary become proportionally larger. There is a much greater change in the length of the plume than the girth, (width, diameter) as you will see in the demos. The mist has weight and carries with gravity. Even though the mist is light it falls.
