* 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 eductors on oil product and chemical ship tankers
* Inspirators mix air and flammable gas in grills, gas stoves, Bunsen burners and airbrushes
* Water aspirators produce a partial vacuum using the kinetic energy from the faucet water pressure
* Steam siphons use the kinetic energy from the steam pressure to create a partial vacuum
* Atomizers disperse perfume or spray paint (i.e. from a spray gun)
* Carburetors use the effect to suck gasoline into an engine's intake air stream
* Cylinder heads 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 aerators infuse air into wine as it is poured into a glass
* Protein skimmers filter saltwater aquaria
* Automated pool cleaners use pressure-side water flow to collect sediment and debris
* Clarinets use a reverse taper to speed the air down the tube, enabling better tone, response and intonation
* The leadpipe of a trombone, affecting the timbre
* 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.
* 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 scuba diving regulator uses the Venturi effect to assist maintaining the flow of gas once it starts flowing
* In recoilless rifles to decrease the recoil of firing
* The diffuser on an automobile
* Race cars utilising 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 tunnels 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.
