What is an Orifice?

An orifice is a small opening provided on the side or bottom of a tank, through which a fluid is flowing. The opening can be of any shape or cross-section, like rectangular, triangular or circular. The orifices may discharge fluid into the atmosphere or from one tank to another.

Orifices are classified based on the shape or the cross-sectional area as:
  • Rectangular orifice
  • Circular orifice
  • Triangular orifice and
  • Square orifice
Orifices are classified based on the size of the orifice and the head of fluid above the orifice as:
  • Small orifice and
  • Large orifice
Depending on the shape of the upstream edge of the orifices, they are classified as:
  • Sharp-edged orifice and
  • Bell-mouthed orifice
They are also classified based on the nature of the discharge as:
  • Partially submerged or drowned orifice
  • Fully submerged or drowned orifice
  • Free discharging orifices
