Which unit is used to express the diameter of the distribution pipe in the example?

Explanation:
Pipe diameter in distribution systems is typically given in inches because U.S. water practice uses nominal pipe size (NPS) measured in inches for pipes, fittings, and valves. This standard aligns with manufacturer catalogs and design references, so diameter is conveyed in inches rather than feet, meters, or centimeters. Feet describe length, and the metric units are not the norm in this context. So, the example expresses the distribution pipe diameter in inches.
