help understanding nozzle chart

[Scott Daniell]

I have an 8gpm/3500psi machine. If I want to lower the pressure to 500 psi would I use an orifice size of 30.0? Thanks

I know it's a little small, but if you read across the top to 500 PSI, then trace down to the GPM (7.07, 8.84) you can see the 8 GPM is in the middle somewhere. Now read back to the left for the nozzle size. The #20 is going to net about 650 PSI, the #25 will net about 350 PSI. If you want exactly 500, I'd use the #20 and turn the unlader down a bit. Of course, then you'll be down to a little over 6 GPM, too.

By the way, welcome to PWI.
