Abstract
Is a Hazen and Williams friction loss factor of 120 adequate to allow for deterioration in sprinkler piping over the years? Just how much deterioration does take place and what are the factors contributing to it? This analysis was made for the Fact Finding Committee of the National Automatic Sprinkler and Fire Control Association.
