The frictional head loss can be calculated using a mathematical relationship that is known as Darcy's equation for head loss. The equation takes two distinct forms. The first form of Darcy's equation determines the losses in the system associated with the length of the pipe. where: Example: Darcy's Head Loss Equation A … See more 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 … 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 … 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 rate. This relationship can be found by … See more The losses that occur in pipelines due to bends, elbows, joints, valves, etc. are sometimes called minor losses. This is a misnomer because in many cases these losses are more important than the losses due to pipe friction, … See more Webwhere is: q - discharge flow rate [l/min]; d - internal pipe diameter [mm]; hL - head loss [m]; K - resistance coefficient [ - ]; This equation can be used for offtake calculation from pipes, fittings and valves when resistance coefficient K, static head difference hL and internal pipe diameter d is known. The resistance coefficient is the sum ...
