okay, my letcerur for mechanics of fluids asked me about this question and damn!! i can't answer it eventhough I'm in engineering course,so people who knows the answer,please help me!! thank you.

Strongest shape to resist pressure
Gives lowest surface area for a given volume flow (hence lowest resistance)
Easiest to manufacture

Aside from the fact that it is a strong and simple design that can be manufactured relatively easily, I think you need to look at the sustainability as well.
When analyzing piping systems, the vast majority of areas that cause cause failures are those with non-linearities. These could be changes in thickness, flanges, valves, welds, connections, etc... With a circular pipe, there really isn't really any concentration of force on any one specific area within the pipe and rather it is spread out evenly which allows the material to essentially withstand higher stresses. This is also a reason why the design is so strong.

Several reasons.
1. You get a better volume to area ratio as your not losing anything at corners.
2. You don't have gunk buildup in crevices or corners
3. It allows you to make air tight piping better for say a gas line. Your able to have a ball valve which when turned correctly can create an air tight tube in case you need to shut your gas line of or something.
4. Reduction of water hammer which in turn reduces wear and tare on pipes (search water hammer if your not aware of what it is)
5. Less leaking because there are no corners which are prone to wear and tear and will leak first.

Um, which cross-section of pipe can hold (and transport) the most amount of fluid while using the least amount of metal (or plastic, or whatever the pipe is made of)?
That would be a circle...think of it as maximizing area per perimeter.

A circle is the most efficient hydraulic cross section. A little calculation with different shapes wil prove to you that for a given cross sectional area (and, therefore, capacity) the circle has the smallest circumference when compared to other shapes. BY minimizing the circumfernce you have minimized the area exposed to friction and therefore minimized friction losses.

A circular cross-section for a pipe gives the maximum internal pressure capacity per volume of construction material. There are manufacturing advantages as well.

Circular form maximizes the volume with least surface area so ultimately is cheaper to manufacture less material.
Circular is very easy to extrude, so cheaper to manufacture.
Circular form is much stronger than square or rectangular form. Pressure is evenly distributed. Edges in corners will undergo much higher stress than round.
Circular form lends it self very easy to smooth bends and turns. rectangular is much more difficult to fabricate.
From a fluid dynamics perspective, liquids like to flow in round better than rectangular.

It is easier to extrude. It wont have the corners were crud will travel. Can you see trying to join square pipes together with pipe threading like they do with round pipes? If threading wont work how wold they join them together. With a non circular cross section, the amount of cavitation would increase tremendously. Look up the cause of cavitation.

I made an A in fluid mechanics, and i can't understand you, could you please ask it in a more proper way?
"Why pipe in circle form" is not even in proper English format!
