Worth knowing about this source
The brackets of the Hazen-Williams equation come through as characters nobody can type. Read the equation in the guide itself before relying on it.
Why the wording is not on this page
This is a US government work, free to quote and cite. The corpus reads it page by page from the official copy, and a citation names a page of it, so this page says what the document is, which edition it is, and links that copy.
How a question cites it
A citation to this document carries the page number of the file this site read, an exact quote, and the anchor of the page it is on, which counts the pages of the file and not the numbers printed on them. You can check every claim against the copy linked above.
