    Default an size vs flow

    Where is Bob when you need him?
    You guys... someone has this chart next to them now...
    I need to know flow in gpm of a -10 vs a -12 at 5 psi nominal pressure.... (don't worry about bends, turns, distance, etc... both will be similar for my purpose)
    I used to have some little machinists bible... it is toast.
    Thanks

    Wow, that is better than I thought.
    a 1/2" ID line will flow 15 gpm.....
    A 5/8 OD line with ,035 wall ish... will flow around 18 gpm.....
    I am working on an alky piece for a monster truck goofball. His manifold has 1/2" pipe outlets. I will open them up to 3/4 pipe.. plenty of room in the manifold, run 5/8 of line, T them together to a -12.... and have plenty of flow out...
    Thanks

    (yes, I understand the diff between diameter and area.... so it is somewhat surprising... just that it is that much, not 1/2 vs 5/8)

    Here is a sample of some nozzles I flowed a month ago.
    These were all NEW ! Pretty typical.
