This example, from an Airbus A380, combines a pitot tube (right) with a static port and an angle-of-attack vane (left). Air-flow is right to left. Types of pitot tubes A pitot-static tube connected to a manometer Pitot tube on Kamov Ka-26 helicopter A Formula One car during testing with frames holding many pitot tubes Location of pitot tubes on ...
The basic technology of the pitometer log is similar to that of the pitot tube on an aircraft. Typically, the pitometer has a long tube that penetrates the ship's hull near the keel. The part of the pitometer protruding from the ship is sometimes called a pit sword or rodmeter. This tube usually has two openings: one facing the direction of ...
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
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.
The two points of interest are 1) in the freestream flow at relative speed where the pressure is called the "static" pressure, (for example well away from an airplane moving at speed ); and 2) at a "stagnation" point where the fluid is at rest with respect to the measuring apparatus (for example at the end of a pitot tube in an airplane).
In the three-hole kind of instrument, there are two yaw direction tubes which are chamfered and silver soldered symmetrically on the two sides of a pitot tube. It is otherwise similar to the other kinds of yawmeters. In the four- and five-hole configurations, the central pitot tube is surrounded by three or four chamfered tubes, respectively.

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 ...
