Observe Pattern and Atomization Changes

to drop off after that but a 515 tip became a 517 tip just after 20 gallons after 60 gallons the orifice size yo is it was significantly bigger and what actually happens is the pattern begins to change so the pattern is kind of like a nice oval looking pattern the droplet size is nice and even and as the tip begins the wear the orifice size begins to wear what happens is that pattern is having a nice um oval shaped pattern it starts to become a circular pattern and what happens is the atomization process isn't um is effective it isn't as good droplet size is more sporadic larger and smaller droplets intermix and what happens is you start to get a lot more overspray a lot more fallout so when you're spraying especially overhead as the tip begins to wear you start to feel more droplets falling out of the air on you and that is a worn tip size now some of the overspray some of the fallout's going to be related to uh pressure um too high pressure is going
