[punctured]

I always see radiators with 180 degree bends. I was wondering (bad thing to do) if a completely circular radiator would actually help cooling? Water entering at the outer edge, exiting from the center.

I figured it would help keep flow at a high rate, but you never see a design like this (or atleast I haven't). Then you always read where people say that bends cause the flow rate to decrease.

Just a random thought and curious as to whether or not it would actually benefit at all.
