    Flow resistance in piping bends

    I've been comparing Fig 2-16 and the table on Page A29 in Crane Tech Paper 410 which both purport to show Kb versus r/d. The Fig 2-16 shows experimental data for Kb versus r/d which starts at values of Kb about 0.35 to 0.4, dips to about 0.2 at r/d = 4 and rises roughly to a plateau at r/d > say...
