WebAn orifice may be defined as an opening provided in the side or bottom of a tank, for the purpose of discharging the liquid contained in the tank. It should be noted that the opening will be considered as an orifice only when the liquid surface in the tank is above the upper edge of the opening. Orifices may be classified based on their size, shape, sharpness …
