venturi effect

This term describes a specific physical phenomenon where fluid velocity increases and pressure decreases as it passes through a narrowed channel. It is a practical application of Bernoulli's principle and is most commonly encountered in mechanical engineering and fluid dynamics.

In technical communication, the term is used to explain the operational logic of devices like carburetors, aspirators, and certain types of flow meters. It is a precise scientific term and is rarely used in casual conversation unless referring to specific engineering or aerodynamic contexts.
