Head loss chart
WebThe term friction loss (or frictional loss) has a number of different meanings, depending on its context.. In fluid flow it is the head loss that occurs in a containment such as a pipe or duct due to the effect of the fluid's viscosity near the surface of the containment.; In mechanical systems such as internal combustion engines, the term refers to the power … WebMay 22, 2024 · The head loss (or the pressure loss) represents the reduction in the total head or pressure (sum of elevation head, velocity head and pressure head) of the fluid …
