Headloss through a reducer

WebHazen and Williams created an empirical formula to calculate pressure losses for liquids flowing through straight pipes. The formula below can calculate these losses over a given length of pipe. ... (L/s). Employ the Hazen-Williams equation to calculate the pipe's head loss. Solution: h L = 10.67 * L * Q 1.852 / C 1.852 / d 4.87. h L = 10.67 ... WebOct 1, 2012 · This situation (all flow in branch, no flow in run) is described by Idelchik 3rd Ed Fig 7-8. This shows a K value of 0.6 at Re = 4,000, decreasing to a K of 0.5 at Re = 40,000 for a 45 degree wye. These values are slightly more than double what I would expect for a long radius 45 degree bend. But at the velocities normally used in pump suctions ...
