WitrynaIn a small orifice, the size of the orifice is so small compared with the head over it, the velocity at the level of the centre of the orifice may be taken as the mean velocity through the orifice. In a large orifice however, this is not correct. An orifice may be circular, rectangular or square though often, circular orifices are adopted. WitrynaThe resistance coefficient K is considered to be constant for any defined valves or fittings in all flow conditions, as the head loss due to friction is minor compared to the head loss due to change in direction of flow, obstructions and sudden or gradual changes in cross section and shape of flow.
