Random but I finally measured my water meth output at the nozzle.
I tried DO3, 4 and 5 nozzles with my old Snow 40220A pump, which is a 300 psi pump but I understand they turn it down to something like 200(?) psi from the factory. Either way it's at the factory setting.

So very simple, DO3 was 150ml a minute
DO4 was 200 ml a minute
DO5 was 250 ml a minute.

Honestly I'm not sure what the right size nozzle is. I was getting bogged down definitely with both #5 and also #4 if I recall right. I don't remember the full details of when I had it coming on initially. I'm using the 3 now but it seems too small on paper...

Any thoughts as to these flow rates?
Is there a guideline of water meth flow rate compared to fuel flow rate or air flow rate?
