Experiment 5 - eng.fsu.edu

This loss in pressure is mainly due to the fact that flow separates locally as it moves through such fittings. The pressure loss in pipe flows is commonly referred to as head loss. The frictional losses are referred to as major losses (h l) while losses through fittings, etc, are called minor losses (h lm).

The level of friction loss depends on a nuer of factors: The material the pipe is made from - a rougher inner pipe surface will result in a greater friction loss. The velocity of the liquid through the pipe - the higher the velocity, the greater

9. FRICTION LOSS ALONG A PIPE - FIT Staffweb

Loss of head is incurred by fluid mixing which occurs at fittings such as bends or valves, and by frictional resistance at the pipe wall. Where there are numerous fittings and the pipe is short, the major part of the head loss will be due to the local mixing near the fittings. For a long pipeline, on the other hand, skin friction at the pipe wall

Pressure drop in pipe fittings and valves | equivalent

In long pipelines most of the pressure drop is due to the friction in the straight pipe, and the pressure drop caused by the fittings and valves is termed the "minor loss". As pipes get shorter and more complied the proportion of the losses due to the fittings and valves gets larger, but by convention are still called the "minor losses".
