In 2007, field tests were conducted by the Greater Cincinnati
Water Works (GCWW) to evaluate the Hazen-Williams
C-values throughout the distribution system. The C-value
tests were conducted with the use of a hydrant diffuser
assembly. This poster paper shows
how the use of a hydrant diffuser can result in
higher than actual calculated flows and an artificially high
C-value. It presents the results of the field tests conducted for
the GCWW, shows the magnitude of the error that can potentially
be introduced using hydrant diffusers, and presents a
recommended correction to use when calculating flows
using a hydrant diffuser.
