Definition

1. Noun:
   • A short tube inserted into a pipeline and used to measure the quantity of a liquid that is flowing in the pipeline: A Venturi tube is a specific device consisting of a tube with a constricted section, designed to measure fluid flow rate based on the pressure difference between the wider and narrower parts.

Usage Examples

• Noun:
  • The engineer installed a venturi tube to monitor the water flow in the main supply line.
  • Accurate measurement of fuel flow was achieved using a calibrated venturi tube.

Advanced Usage

• "Venturi effect": The physical principle upon which the venturi tube operates, where the pressure of a fluid decreases as its velocity increases when it flows through a constricted section of pipe.
  • The design utilizes the Venturi effect to create a pressure differential for measurement.

Variants and Related Words

• Venturi meter (n): Another term for a venturi tube, specifically when used as a measuring instrument.
  • The venturi meter provided precise data on the flow rate.

Synonyms

• Flow meter: A general term for a device that measures the flow rate of a fluid.
• Constriction meter: A descriptive term highlighting the constricted design of the device.

Related Phrases

• To employ a venturi tube: To use a venturi tube for a specific measurement purpose.
  • The laboratory procedure employs a venturi tube to determine the liquid's velocity.
