I guess being old and having been around for a long time. The 32 ft per

above that velocity the friction loss gets larger

also look at 13: A.22.4.1 (last sentence) It is not necessary to
restrict the water velocity when determining friction loss using the
Hazen-Williams formula.
This is also in the 02 edition.
