Venturi

Definition
- Noun:
- A tube with a constriction: A device consisting of a tube that narrows to a throat (a constriction) and then widens again, used to measure or control the flow rate of a fluid (liquid or gas). The change in diameter causes a change in fluid pressure and velocity according to Bernoulli's principle.
- A person (proper noun): Robert Venturi, an influential American architect.
Examples of Usage
Noun (Device):
- The engineer installed a venturi in the pipeline to measure the flow of water.
- A carburetor uses a venturi to create a vacuum that draws fuel into the airstream.
- The increase in fluid speed through the venturi causes a drop in pressure.
Noun (Person):
- Venturi was a leading figure in postmodern architecture.
- The design principles of Venturi challenged modernist orthodoxy.
Advanced Usage
- Venturi effect: The reduction in fluid pressure that results when a fluid flows through a constricted section (the throat) of a pipe. This is the core physical principle applied by a venturi device.
- The Venturi effect is exploited in many spray nozzles and aspirators.
- Venturi meter: A specific instrument that uses a venturi tube to measure the volumetric flow rate of a fluid.
- The Venturi meter provided accurate flow data for the experiment.
Variants and Related Words
- Venturi tube: Another term for the venturi device itself.
- Venturimeter: A synonym for venturi meter.
Synonyms
- For the device: constriction tube, flow tube, differential pressure flow meter.
- For the person: Robert Venturi, Robert Charles Venturi Jr.
Related Phrases
- Venturi scrubber: A pollution control device that uses the venturi effect to remove particles from an exhaust gas stream.
- The factory installed a Venturi scrubber to clean its emissions.
Noun
- a tube with a constriction; used to control fluid flow (as in the air inlet of a carburetor)
- United States architect (born in 1925)
