text: * 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.
