Circle vs. Square Port

Curious to what REALLY makes a circle shaped power (pvc/aero/sonotube) more efficient that a square port (slot). :WTFBubble:

The corners in slot and square ports are dead areas that the air doesn't move to so a round port allows all of the air to travel through it. Plus you have more surface area which creates friction for the air to pass through which slows it down, but many times it is just easier to make a slot port than to try and find a size in round ports suitable for use.
