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 coustion engines, the term refers to the power lost in overcoming the friction between two moving surfaces, a different phenomenon.

Friction Loss Charts | Rain

Friction Loss Charts There are many components to an irrigation system which all factor into its overall performance, yet the heart of an efficient system is good design. Rain supports the use of trained irrigation professionals for system design and installation. The following charts provide reference data for the loss of pressure due to friction in various pipe sizes that should be

Calculating Horsepower Requirements and Sizing Irrigation

Friction loss: Water flowing past the rough walls in a pipe creates friction which causes a loss in pressure. Friction losses also occur when water flows through pipe fittings, or when the pipe suddenly increases or decreases in diameter. Tables with values for friction loss through pipe and fittings similar to Tables 6 and 7 are widely available.
