Solid Stream Nozzles for Cleaning

This design of nozzles is relatively simple.  It  consists of a shaped orifice to focus the fluid into a narrow jet. These nozzles produce the highest impact of any nozzle for any given flow rate or pressure.  This is because the potential energy of the fluid is concentrated into a very small area.

Momentum loss

All sprays begin to lose momentum after they leave the orifice.  As they lose momentum the spray pattern will begin to break up.  This is particularly problematic for solid stream nozzles as momentum, and hence impact loss, can be very rapid once the solid stream pattern starts to dissipate. ,There are two solutions to this problem.

The first is to simply keep the target very close to the nozzle.  To aid with this solid stream nozzles come in low profile variants meaning the nozzle can be brought within a cm or so of the target if necessary.  Bete's range of "Shower" nozzles are very low profile nozzles designed for use in high pressure wash showers. 

The second solution is to ensure that the exit orifice is as smooth and unworn as possible.  Tiny imperfections can rapidly lead to the turbulent flows that break up the solid stream pattern.  Hard wearing materials like ruby and ceramics will not only resist wear much longer but they can also give an incredibly smooth orifice.  In the case of rubies the orifice is laser bored for a supremely smooth finish.
