Editing Venturi effect (section)

===Machines===
* During [[Underway replenishment]] the [[helmsman]] of each ship must constantly steer away from the other ship due to the Venturi effect, otherwise they will collide.
* Cargo [[Eductor-jet pump|eductors]] on oil product and chemical ship tankers
* [[Inspirator]]s mix air and flammable gas in [[Grill (cooking)|grills]], [[gas stove]]s and [[Bunsen burner]]s
* [[Water aspirators]] produce a partial vacuum using the kinetic energy from the faucet water pressure
* [[Steam injector#Vacuum ejectors|Steam siphons]] use the kinetic energy from the steam pressure to create a partial vacuum
* [[Atomizer nozzle|Atomizers]] disperse perfume or spray paint (i.e. from a spray gun or [[airbrush]])
* [[Carburetor]]s often use the effect to force [[gasoline]] into an engine's intake air stream at the throat by the difference between the pressure there and at the upstream start of the converging wall (which is fed to the float bowl). In other carburetors ambient air pressure can be fed to the float bowl, in which case the effect comes from [[Bernoulli's principle]].
* [[Cylinder head]]s in piston engines have multiple Venturi areas like the valve seat and the port entrance, although these are not part of the design intent, merely a byproduct and any venturi effect is without specific function.
* [[Wine aerator]]s infuse air into wine as it is poured into a glass
* [[Protein skimmer]]s filter saltwater [[aquarium|aquaria]]
* [[Automated pool cleaner]]s use pressure-side water flow to collect sediment and debris
* [[Clarinet]]s use a reverse taper to speed the air down the tube, enabling better tone, response and intonation<ref>{{Cite web|url=https://www.face2fire.com/venturi-or-air-circulation-thats-the-question/|title=Venturi or air circulation?, that's the question.|last=Blasco|first=Daniel Cortés|website=face2fire|language=es|access-date=2019-07-14}}</ref>
* The [[leadpipe]] of a [[trombone]], affecting the [[timbre]]
* Industrial [[vacuum cleaner]]s use compressed air
* [[Venturi scrubber]]s are used to clean [[flue gas]] emissions
* Injectors (also called ejectors) are used to add chlorine gas to [[water treatment]] [[Water chlorination|chlorination]] systems
* [[Injector|Steam injectors]] use the Venturi effect and the [[latent heat]] of evaporation to deliver feed water to a [[steam locomotive]] [[boiler]].
* [[Sandblasting]] nozzles accelerate and air and media mixture
* [[Bilge]] water can be emptied from a moving boat through a small waste gate in the hull. The air pressure inside the moving boat is greater than the water sliding by beneath.
* A [[diving regulator|scuba diving regulator]] uses the Venturi effect to assist maintaining the flow of gas once it starts flowing
* In [[recoilless rifle]]s to decrease the recoil of firing
* The [[Diffuser (automotive)|diffuser]] on an automobile
* Race cars utilising [[Ground effect (cars)|ground effect]] to increase [[downforce]] and thus become capable of higher cornering speeds
* Foam proportioners used to induct [[fire fighting foam]] concentrate into fire protection systems
* [[Trompe]] air compressors entrain air into a falling column of water
* The bolts in some brands of paintball markers
* Low-speed [[wind tunnel]]s can be considered very large Venturi because they take advantage of the Venturi effect to increase velocity and decrease pressure to simulate expected flight conditions.<ref>{{cite book |last1=Anderson |first1=John |title=Fundamentals of Aerodynamics |date=2017 |publisher=McGraw-Hill Education |location=New York, NY |isbn=978-1-259-12991-9 |page=218 |edition=6th}}</ref>
