Determing flow of a closed loop parallel pumping system

    Hi all,

    How would one go about determining the flow(GPM) of a closed loop parallel piping system.
    I believe this has to do with the pressure intake and outlet of the pump as I have a pump in the mentioned system rated at 4350GPM@50Hz but it is pumping at 4500 GPM at 37Hz,

    Thank you all for your time in advance.

    Regards,
    D

    You mean you want to add a second pump in parallel? Knowing the flow and pressure - assuming it is a constant flow situation - enables you to model the system curve, the identify where that crosses the pump curves.
