Definition
Noun: 1. A measuring instrument for fluid flow velocity: A device, specifically a right-angled tube with an open end pointed into a fluid stream, used to measure the flow's velocity based on pressure difference. 2. The namesake of the instrument: Henri Pitot, a French physicist (1695–1771) who invented the Pitot tube.
Usage Examples
- The aircraft's airspeed indicator relies on data from the pitot.
- Engineers calibrated the pitot to ensure accurate water flow measurements in the pipe.
- The principle behind the pitot tube was established by Pitot in the 18th century.
Advanced Usage
- Pitot-static system: A combined aircraft instrument system that uses a pitot tube (for dynamic pressure) and static ports (for ambient air pressure) to determine airspeed, altitude, and vertical speed.
- Example: Ice blockage of the pitot-static system can cause erroneous instrument readings.
Variants and Related Words
- Pitot tube (noun phrase): The full, most common term for the instrument.
- Pitot head (noun phrase): Another term for the pitot tube, often referring to its external mounting assembly on an aircraft.
Synonyms
- Flow sensor (general term)
- Anemometer (specifically for measuring wind speed, often using a different principle)
Related Phrases
- Pitot pressure: The pressure measured at the open end of a pitot tube, representing the stagnation or total pressure.
- Pitot inlet: The opening at the front of a pitot tube that faces the fluid flow.
Noun
- measuring instrument consisting of a right-angled tube with an open end that is directed in opposition to the flow of a fluid and used to measure the velocity of fluid flow
- French physicist for whom the Pitot tube was named (1695-1771)
