Thanks Bill,

I'm kind of wondering if the difference might boost the output flow from
16 GPM to the 20 GPM advertised or is it something to do with the way
I'm testing.  

I still need to think about the square law and see if I can salvage
anything from my calculations. Does it matter if flow is laminar or
turbulent and aren't engine blocks and radiators intended to use
turbulent flow?
