I have a pressure washer with 5gpm and 2500 psi. Would tip size and orifice should I use in order to bring the pressure down enough to strip fences and decks.
900 psi at the tip is usually fine for 6" decking. Softwoods such as cedar a bit less, but no need to change tips, just keep the wand further away from the wood. It is immediately obvious if you are damaging wood with too much pressure.
Chemical strippers are what do the work, not water pressure. A PW on wood is kind of like a glorified scrub brush. 5 GPM is ideal.

Bump I have the same machine … 5.5 gpm 2500 psi what nozzle would bring it down around 800 psi… would it be a 2510 nozzle??

Here you go guys - you can find nozzle charts all over the web. Learn to use
Realize that if you’re running couple hundred ft of hose your pressure may be a little less so account for that

Yep, that’s right
I can appreciate the scientific approach to stripping a wood surface, but I take a common sense way to do this. W (white/40 degree tip) is for wood. Always start rinsing about 5-6 inches from the surface and get closer if needed so as not to"furr" the wood. The right chems and cleaners make the difference between blasting the job and rinsing off a deck. It’s my lasagna pan theory I explain to homeowners and they"get it" then. In the end, it’s all about the dwell time. They both clean up easier after they have been allowed to soak for about 30 minutes. Hope this helps.
I explain (educate) to customers regarding tips and their use like a stoplight:
Red= STOP.
Yellow= proceed with caution
Green= Go
White= Wood
