In plumbing, what is referred to as a cross-section?

In plumbing terminology, a cross-section refers to the shape of a pipe when it is cut through at any specific point, which gives a view of its internal configuration. This term is crucial for understanding how pipes and systems work both functionally and structurally.

While the point where potable (safe for drinking) and non-potable (not safe for drinking) water meet might be a significant concern in plumbing regarding cross-contamination and health standards, it does not define a cross-section. The concept of a cross-section primarily relates to the physical characteristics of a pipe or any other plumbing feature rather than the specific context of water types meeting.

Understanding what a cross-section is can greatly aid in grasping various plumbing designs and issues, such as flow rates, pressure, and the potential for sediment buildup within a pipe.
