2. Venturi effect - Wikipedia

   en.wikipedia.org/wiki/Venturi_effect

   Industrial vacuum cleaners use compressed air; Venturi scrubbers are used to clean flue gas emissions; Injectors (also called ejectors) are used to add chlorine gas to water treatment chlorination systems; Steam injectors use the Venturi effect and the latent heat of evaporation to deliver feed water to a steam locomotive boiler.

3. Vacuum ejector - Wikipedia

   en.wikipedia.org/wiki/Vacuum_Ejector

   A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

4. Choked flow - Wikipedia

   en.wikipedia.org/wiki/Choked_flow

   For air with a heat capacity ratio =, then =; other gases have in the range 1.09 (e.g. butane) to 1.67 (monatomic gases), so the critical pressure ratio varies in the range < / <, which means that, depending on the gas, choked flow usually occurs when the downstream static pressure drops to below 0.487 to 0.587 times the absolute pressure in ...

5. Vacuum cleaner - Wikipedia

   en.wikipedia.org/wiki/Vacuum_cleaner

   Smaller versions, for use in garages or small workshops, are usually electrically powered. Larger models, which can store over 200 litres (44 imp gal; 53 US gal), are often hooked up to compressed air, utilizing the Venturi effect to produce a partial vacuum.

6. Venturi scrubber - Wikipedia

   en.wikipedia.org/wiki/Venturi_scrubber

   The ejector venturi is unique among available scrubbing systems since it can move the process gas without the aid of a fan or blower. The liquid spray coming from the nozzle creates a partial vacuum in the side duct of the scrubber. The partial vacuum is due to the Bernoulli effect, and is similar to water aspirators used in chemistry labs ...

7. Manifold vacuum - Wikipedia

   en.wikipedia.org/wiki/Manifold_vacuum

   Venturi vacuum is caused by the venturi effect which, for fixed ambient conditions (air density and temperature), depends on the total mass flow through the carburetor. In engines that use carburetors, the venturi vacuum is approximately proportional to the total mass flow through the engine (and hence the total power output).
