The restriction or resistance to flow rate, is a property of a system, however, this also varies with flow rate.
The number of volts applied across an electrical circuit is not a physical property of that circuit is it. It is something we have applied, much like a head loss or pressure drop in a liquid circuit.

Hi mate
Btw, check Xtreme thread
WC system is like electrical system with all the 'bits' installed so we are not applyiing anything, all we do is provide different power source (diff pumps) but performance of regular electrical components is linear (guessing here since I am not that conversant with electrics/electronics) and with stronger amps or volts resistor is going to produce the same resistance (hence watts ratings) all the time (lame example?).
Anyways, at diff flows restriction posed by a system as a whole is different, absolutely right. All I am saying is that an assembled system has just one flow-to-head curve dependant only on hardware from which it was made off. Curve doesn't change, values on it do
