Thanks Roland, John again, and Ron again. This post is for adjusting the K-Factor for fluid properties other than water at ~40F, 62.4 lb/ft3, not for 'pure' water flowing through an area that varies a couple hundredths of a square foot. See 13-2007, A.22.4.4.5.1, which, if deleted in later editions, would be shame. Thanks to everyone again. Brad
