Pump head and flow rate relation

  1. i need some help becoase i become confused
    according to pump characteristic curve if the flow rate increased the head will decreased
    the question is how i can increase the flow rate and what is the relation of RPM with head and flow rate

  4. thank u for ur answer but this link is speake about changing rpms it is available to change the pump head by change pump capacity with constant RPM and how ?

    By combining the first and second equations, you get an equation that tells you that by lowering the pressure resistance in the system, you'll get an increase in flow.
