WebMinor pressure and head loss in pipes vs. equivalent length in tubes and duct systems. Pressure loss in straight pipes or ducts are called the major, linear or friction loss. Pressure loss in components like valves, bends, tees and similar are called the minor, dynamic or local loss. Minor loss can be significant compared to major loss.

WebNov 5, 2008 · In summary, pumps and elevation drops add head to a plumbing system while elevation rises, pipes, fittings, valves, filter, heaters, etc. subtract head from a system. For a swimming pool, the total head loss is always equal to the pump's head gain since the water is returned to the same atmospheric pressure as where it came from. Water Velocity WebMar 5, 2024 · The pressure difference (P out-P in) between two points in the pipe is due to the frictional resistance, and the head loss h L is directly proportional to the pressure difference. The head loss due to friction can be calculated from the Darcy-Weisbach equation: where:: head loss due to flow resistance. f: Darcy-Weisbach coefficient. L: …
