For example, the velocity of a fluid is close to 0 feet per second. But in a pipeline the fluid must be accelerated, resulting in a change of momentum. That change is lost to friction. L/D Coefficient The L/D coefficient is often used to determine the head loss in a valve or fitting.
Web16 jan. 2016 · The frictional resistance generates a continuous loss of energy or total head in the fluid and hence decreases the pressure of the fluid as it moves through the pipe. There are four factors that determine friction losses in pipe. i. The velocity of the fluid. ii. The size (inside diameter) of the pipe. iii. Web24 apr. 2024 · 14. Loss of head due to bend in the pipe When there is any bend in a pipe, the velocity of flow changes due to which the separation of the flow from the boundary takes place, there is also formation of eddies. Which results in a loss of energy or head. This loss of head or energy as expressed as 14. 16.
