Please rephrase to an "imaginary" system with a very low restriction, since the head loss varies with flow rate. It is NOT constant.
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.
