Definition
A Venturi is a tube or passage with a constriction in it that causes a decrease in pressure and an increase in fluid velocity.
Examples
  • The Venturi tube is a common piece of equipment in fluid dynamics experiments.
  • When air passes through the Venturi, it speeds up and lowers the pressure, which can draw in additional air or liquids.
  • Cars often use a Venturi effect in carburetors to mix air and fuel efficiently.
Meaning
The Venturi effect illustrates how the pressure of a fluid decreases as its velocity increases when passing through a constricted section of pipe.
Synonyms
