"Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system. Head loss is unavoidable in real fluids. It is present because of: the friction between the fluid and the walls of the pipe; the friction between adjacent … See more The friction factor has been determined to depend on the Reynolds numberfor the flow and the degree of roughness of the pipe's inner surface. The quantity used to measure the roughness of the pipe is called the relative … See more The frictional head loss can be calculated using a mathematical relationship that is known as Darcy's equation for head loss. The equation takes … See more Minor losses may be expressed in terms of the equivalent length (Leq) of pipe that would have the same head loss for the same discharge flow … See more The losses that occur in pipelines due to bends, elbows, joints, valves, etc. are sometimes called minor losses.
