WebIn 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. WebA fluid passing though an orifice constriction will experience a drop in pressure across the orifice. This change can be used to measure the flowrate of the fluid.
