F D C Air Flow and Air Friction Thermaflex

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

The friction loss is customarily given as pressure loss for a given duct length, ?p / L, in units of (US) inches of water for 100 feet or (SI) kg / m 2 / s 2. For specific choices of duct material, and assuming air at standard temperature and pressure (STP), standard charts can be used to calculate the expected friction loss.
