Pressure and Nozzle Size

Rapid HotClean said:
Is there a rule of thumb as to pressure and nozzle size. For example, does doubling the oraface size cut the pressure by 50%?

No. It has to do with volume. The way they have it set up is based on 4000 psi. So if you have a 4 gallon per minute machine, rated at 4000 psi,you would use a #4 nozzle, since you can't double it, cut it in half and you need a #6 nozzle for 2000 psi. If you have a 5.5 gpm machine and need 1500 psi you use a #9 nozzle. If you need 3000 psi you need a #6.5 nozzle. So I don't see any rule of thumb out of that. They are all over the place based on what volume your pump is putting out.
