Tubing and fittings will have flow resistances that very with flow rate.
They will not have high resistance when compared to the WB and radiator, so you might as well assume these resistances are negligible.
The PQ curve for most flow restrictions is much more complicated than a simple square relationship.
Oh, and after some thought I believe determing flow rate won't require much calculation at all. Simply add the PQ functions for the flow restrictions and find where the point in that curve correlates with the PQ curve for the pump.
Quite easy, I think, to just subtract one function from the other and find the zero.
