[Equest-users] request concerning pump power curves for eQuest

I am trying to review a proposed modification to the pump power curve in an eQuest model of a variable flow chilled water system. Please explain how the pump power curve works (PUMP-POWER-fFLOW). The quadratic equation appears to give a dimensionless factor between 0.37 and 1.0 for a range of inputs between 0 and 1.0... Is this factor applied against an internal theoretical power calculation to account for the pump/motor efficiency changes at part load?
Thanks in advance for your help.
