Orifice
Encyclopedia
An orifice is any opening, mouth
, hole or vent, as of a pipe, plate, or a body.
Mouth
The mouth is the first portion of the alimentary canal that receives food andsaliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth....

- Orifice plateOrifice plateAn orifice plate is a device used for measuring the volumetric flow rate. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid...
- Calibrated orificeCalibrated orificeA calibrated orifice is a restriction that is deliberately placed into a system of pipes to set the flow rate through the system. The orifice may be designed to produce proportional flow , or choked flow A calibrated orifice is a restriction that is deliberately placed into a system of pipes to...
