A rounded pipe will reduce molecular friction of the fluid or gas traveling in the pipe. Rounded pipes allow freer, faster flow compared with any other shape.
Circular sewer pipes are preferred because they provide uniform strength and can efficiently withstand the pressure from the surrounding soil and the weight of the water flowing through them. Their shape allows for smooth, uninterrupted flow, reducing the risk of blockages and improving hydraulic efficiency. Additionally, circular pipes are easier to manufacture and install, making them cost-effective for construction projects.
The shape with two circular bases and a curved surface is called a cylinder. In a cylinder, the circular bases are parallel and congruent, connected by a curved surface that wraps around the sides. Common examples of cylinders include cans and pipes.
Because that's the easiest way to make them, and the strongest. EDIT: Also the circular shape allows for a smoother flow of liquid within the pipe and less resistance.
Sewers are typically circular in shape because this design efficiently withstands the internal and external pressures exerted on them. A circular cross-section distributes stress evenly around the pipe, reducing the risk of structural failure. Additionally, circular pipes are easier to manufacture and maintain, allowing for efficient flow and minimizing the risk of blockages. This shape also facilitates the natural flow of sewage, as it helps avoid settling and promotes self-cleansing.
Circular pipes are easy to fabricate and require the minimum material for a given cross section. If the liquid is under pressure, a circular cross section for the pipe holds the pressure easier and allows the stress to be distributed more or less equally around the perimeter; other cross sections will concentrate the stresses in a few areas around the perimeter.
