Major Head Loss – due to friction in straight pipes; Minor Head Loss – due to components as valves, bends…; A special form of Darcy’s equation can be used to calculate minor losses.; The minor losses are roughly proportional to the square of the flow rate and therefore …
WebDec 22, 2024 · Determining the pipe diameter when the pipe length and flow rate are given for a specified pressure drop (or head loss) CH6: Hydraulic Losses in Pipes, Dr . WebJan 19, 2024 · Table 5 shows values of K’ obtained for each pipe at different Cv’s. The circular pipe yields the smallest K’ at the lowest Cv but pipes 2 and 5 yield smaller K’s than does circular pipe at high Cv’s. This suggests that pipes 2 and 5 show a reduction in head loss ratio at the higher Cv’s.
