Fluid Fluid Nozzle Performance
Use the following procedure to select the proper fluid nozzle for your application.
1. For each fluid nozzle chart, find the point on the
graph corresponding to your desired flow rate
and viscosity. Mark the point on each graph with
a pencil.
2. The thick vertical line in each graph represents
the target flow rate for that nozzle size. Find
the graph that has the marked point closest to
the thick vertical line. This is the recommended
nozzle size for your application. Significantly
exceeding the target flow rate may result in
lower spray performance due to excessive fluid
velocity.

3. From the marked point, move across to the
vertical scale to find the required fluid pressure.
If the required pressure is too high, use the next
largest nozzle size. If the fluid pressure is too low
(< 0.35 bar, 3.5 kPa, 5 psi), use the next smallest
nozzle size.
