Ponn hose friction loss coefficient
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 … WebFeb 2, 2011 · where is the mass flux; ρ, the density; S, the area ratio between upstream and downstream pipes; and C c, the contraction coefficient (the ratio of areas of the vena contracta and the outlet pipe.) Equations for the contraction coefficient in terms of S are given by, for example, Benedict (1980) and Chisholm (1986). In gas/liquid flow, the sudden …
