    What type of nozzle?
    What brand of nozzle?
    What type of hose?
    What size hose?

    Do yourself a favor....borrow a flowmeter and read it.

    To add to what Brother Bones stated.. check the nomenclature from the manufacturer.

    On the old original Akron Turbojets, the smaller 30-60-95-125gpm ones, we flow tested them and got roughly 150gpm out of them at 100 psi at the nozzle while on flush. More water, but a crappy stream.

    I was going go into this big long thing about this. But I like your summary much better.

    That is a great screen name, I wish I had thought of that.

    To answer your question you need to know the pressure

    Not too much, enough to flush out the pipe but not enough to have a fire stream and do a lot of firefighting or extinguishment.

    WRONG! With most nozzles on flush if the nozzle pressure is maintained at whatever the nozzle calls for 50, 75, or 100 psi, the nozzle will actually flow MORE water than normal. This occurs because the space between the baffle and the nozzle itself increases, sometimes up to almost a half inch. If the correct nozzle pressure is maintained all you have done is make a higher gpm nozzle by increasing the amount of room for the water to exit the nozzle from. What does tend to happen though is the opening may be TOO big and the stream takes on more of a broken pattern than a true combination nozzle pattern.

    How do I know this? Actual field trials using old style Akron Turbojets with the 30-60-95-125 gpm settings. The pattern would be more than adequate for rooms fires fought from the interior. Not such a good deal for reach needed for exterior streams.

    By the way, we achieved flows in the 150 gpm range at 100 psi NP with the nozzle set on flush.
