Venturi

Definition - What does Venturi mean?

A venturi is a sonic flow nozzle or an abrasive blasting nozzle that consists of an inlet, throat and discharge area. The inlet portion of the venturi is a smooth rounded section that converges to a smaller throat area. When air is sucked inside from an inlet port and passes through the throat, the velocity of the air increases and the air is discharged with a great force from a discharge area or outlet.

Nozzles that make use of the Venturi effect are often used for surface preparation and cleaning equipment.

Corrosionpedia explains Venturi

The simple principle behind the operation of a venturi nozzle is the pressure difference between the inlet of the venturi nozzle and the outlet of the venturi nozzle. The inlet to outlet pressure must be at a ratio of 1.4:1 or greater in order to operate the venturi nozzle as a sonic flow nozzle and to work in an abrasive blasting process. The above principle depends upon the pressure difference between the inlet and the outlet, which is called the Venturi effect. The Venturi effect states that the velocity of a fluid or gas increases as it passes through a constricted section or a choke in a pipe.
