A pitot tube (/ ˈpiːtoʊ / PEE-toh; also pitot probe) measures fluid flow velocity. It was invented by French engineer Henri Pitot in the early 18th century, [1] and modified to its modern form in the mid-19th century by Henry Darcy. [2] .

A pitot tube is an instrument for measuring a flowing fluid’s velocity (speed). Pitot tubes are used in anemometers to calculate airspeed in wind tunnels and aircraft in flight. They also measure the flow of liquids. Let us learn more about pitot tube and their operation in this article.

Jan 3, 2025 · A Pitot tube is a device used to measure the velocity of fluid flow, commonly used in aerodynamics and fluid mechanics applications. It measures both the total (stagnation) pressure and static pressure of the fluid to calculate its dynamic pressure and …

Jun 3, 2016 · Pitot tubes are a common type of insertion flowmeter. The below animation shows the basics for a Pitot tube, where pressure is generated in a tube facing the flow, by the velocity of the fluid.

What is a Pitot Tube? The pitot tube is an inexpensive alternative to an orifice plate, and its accuracy ranges from 0.5% to 5% FS – which is comparable to that of an orifice. Its flow rangeability of 3:1 (some operate at 4:1) is also similar to the capability of the orifice plate.

The pitot tube is a simple and convenient instrument to measure the difference between static, total and dynamic pressure (or head). The head - Δh - (or pressure difference - Δ p) can be measured and calculated with the help of u-tube manometers , electronic pressure transmitters or similar instrumentation.

Pitot tubes were invented by Henri Pitot in 1732 to measure the flowing liquid or air velocity. Basically a differential pressure (d/p) flowmeter, a pitot tube measures two pressures: the static and the total impact pressure.

Jul 8, 2024 · Pitot-Static tubes, which are also called Prandtl tubes, are used on aircraft as speedometers. The actual tube on the aircraft is around 10 inches (25 centimeters) long with a 1/2-inch (1 centimeter) diameter.

Apr 13, 2023 · A Pitot tube is a cylindrical tube having one side open, and the other side closed. The construction part of the Pitot tube includes two hollow tubes to detect the pressure at different regions or locations.

The Pitot tube, for example, senses pressure as the fluid stagnates (comes to a complete stop) against the open end of a forward-facing tube. A shortcoming of the classic single-tube Pitot assembly is sensitivity to the fluid velocity at just one point in the pipe, so a more common form of Pitot tube seen in…
