The pitot tube can be inserted through a small hole in the duct with the pitot connected to a U-tube water gauge or some other differential pressure gauge for determining the flow velocity inside the ducted wind tunnel. One use of this technique is to determine the volume of air that is being delivered to a conditioned space.
This video is an edited approach and landing of the Enterprise on Rogers Dry Lake. The air-to-air shot of the Space Shuttle at a few thousand feet above the lakebed, gives some idea of the steepness required for a Shuttle approach; also note the long pitot tube (an appendage used only for flight testing) extending from the Space Shuttle nose. 1977.
Examples of pitot tube, static tube, and pitot–static tube Static ports fitted to an Airbus A330 passenger airliner. The pitot–static system of instruments uses the principle of air pressure gradient. It works by measuring pressures or pressure differences and using these values to assess the speed and altitude.

A flow of air through a pitot tube Venturi meter, showing the columns connected in a manometer and partially filled with water. The meter is "read" as a differential pressure head in cm or inches of water. Video of a Venturi meter used in a lab experiment Idealized flow in a Venturi tube
None of the pitot tubes were recovered so investigators were unable to determine for certain what caused the blockage. Investigators believe that the most likely culprit was the black and yellow mud dauber ( Sceliphron caementarium ), a type of solitary sphecid wasp well known to Dominican pilots, which makes a cylindrical nest out of mud and ...
Henri Pitot (French: [ɑ̃ʁi pito]; May 3, 1695 – December 27, 1771) was a French hydraulic engineer and the inventor of the pitot tube. In a pitot tube, the height of the fluid column is proportional to the square of the velocity of the fluid at the depth of the inlet to the pitot tube. This relationship was discovered by Henri Pitot in ...
The stationary fluid can be connected to a pressure-measuring device, or used in various devices. For subsonic flow, pitot pressure is equal to the stagnation pressure (or total pressure) of the flow, and hence the term pitot pressure is often used interchangeably with these other terms. For supersonic flow, however, pitot pressure is the ...
Ludwig Prandtl (4 February 1875 – 15 August 1953) [1] was a German fluid dynamicist, physicist and aerospace scientist. He was a pioneer in the development of rigorous systematic mathematical analyses which he used for underlying the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering.
