  • Friction loss - Wikipedia

    In fluid flow, friction loss (or skin friction) is the loss of pressure or head that occurs in pipe or duct flow due to the effect of the fluid's viscosity near the surface of the pipe or duct. In mechanical systems such as internal combustion engines, the term refers to the power lost in overcoming the friction between two moving surfaces, a different phenomenon.
