How to change desired flow rate of the nozzle

  1. Oct 3, 2016 #1
    Hello,

    We have a system with a 70 bar pump and 9 nozzles connected to the pump lines. Total flow rate is 2 l/m. Is there a way to change only one nozzle flow rate manually, with a pressure regulator valf just behind that nozzle?

    Thank you.

    Hello icy, :welcome:

    I suppose 'behind' is relative. With a valve between the pump and the nozzle you should be able to reduce the flow rate. Increasing it would be rather impossible :smile:

    Hello BvU,

    You may see the attached file. It is a simple diagram to see what we need. Can you make a new comment according to the file?

    Thank you.

    BvU's existing comment, as stated, still applies.

    Stream rate directly affects bead estimate. An expansion in stream rate will build the bead measure; comparatively, an abatement in stream rate will diminish bead estimate.

    Case: A 150 gpm empty cone spout at 10 psi has a bigger bead than a 100 gpm empty cone at 10 psi. Likewise, a 50 gpm full cone spout at 7 psi has a littler bead estimate than a 120 gpm full cone spout at the same weight.
