A circle has the most optimal cross sectional area (given the circumference). When it is squashed slightly, it would be a smaller cross section, but the same circumference. You're talking only a slight difference between the two.I have no idea about fluid dynamics (or whatever it's called) but if a circular cross section tube is squashed into an oblong would it still flow the same? The cross section won't have changed, just the shape.
I would have thought overall, it would be likened to adding an unnecessary bend, slowing the flow rate down?
