Orifices are classified based on the following categories: 1. Based on Size. Orifice can be classified as small or large orifice based on the size and the head of fluid in the orifice. 1.1. Small Orifice. If the head of fluid is greater than 5 times the depth of the orifice, then it is categorized as small orifice.

WebMar 21, 2024 · Orifice is defined as the small opening on side or bottom of a tank through which any kind of fluid is flowing. The opening can be of circular, triangular or rectangular in cross section and they are named on the basis of shape accordingly. Orifices are mainly used for measuring the rate of fluid flow. Orifice ( Wikimedia Commons) 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.
