Friction loss

The 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 lost in overcoming the friction between two moving surfaces.

In economics, frictional loss is natural and irrecoverable loss in a transaction or the cost(s) of doing business too small to account for. Contrast with tret in shipping, which made a general allowance for otherwise unaccounted for factors.
