¢ Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe.[1] Friction Loss is considered as a "major loss" and it is not to be confused with “minor loss” which includes energy lost due to obstructions
¢ Friction loss has several causes, including:¢ Frictional losses depend on the conditions of flow
and the physical properties of the system.¢ Movement of fluid molecules against each other¢ Movement of fluid molecules against the inside
surface of a pipe or the like, particularly if the inside surface is rough, textured, or otherwise not smooth
¢ Bends, kinks, and other sharp turns in hose or piping

NUMBEREYNOLDSR¢Reynolds number can be defined for a number of
different situations where a fluid is in relative motion to a surface . These definitions generally include the fluid properties of density and viscosity
