Elliptical orifice flat fan nozzle

With this common design of nozzle the spray pattern is formed by the exit of the fluid through a shaped orifice.


The slightly tapered nature of the flat spray pattern means that spray distribution is not entirely even. The ends of the spray pattern have less fluid delivered. In order to achieve a completely even spray a series of nozzles with slightly overlapping spray patterns should be built. Once the level of spray loss at the edges of the pattern are known this is just a matter of simple trigonometry.
