To find the pipe diameter ($D$) based on a chosen velocity ($v$):
$$D = \sqrt\frac4Q\pi v$$
Note: After calculation, you must select the next standard commercial pipe size (e.g., calculating 3.8 inches leads to selecting a 4-inch schedule pipe).
You cannot size a pipe without understanding the distinction: You cannot size a pipe without understanding the
Critical Module 3 Takeaway: An NPS 4 pipe has the same outside diameter regardless of schedule. However, the inside diameter (ID) shrinks as schedule increases. This changes your velocity and pressure drop drastically. Our exclusive PDF includes a full ID chart for all schedules from 5S to XXS.
