Biographical Note for PITOT TUBE

Pi·tot \pē-tō\ Henri (1695–1771), French hydraulic engineer. Pitot began his career in the chemical laboratory at the Academy of Sciences in Paris.

In 1735 he published a paper announcing his invention of the Pitot tube.

pitot tube

noun    (Concise Encyclopedia)

Instrument for measuring the velocity (speed) of a flowing fluid. Invented by Henri Pitot (1695–1771), it consists of a tube with a short, right-angled bend, which is placed vertically in a moving fluid with the mouth of the bent part directed upstream; the pressure, measured with an attached device, depends on the fluid flow and can be used to calculate the velocity. Pitot tubes are used to measure airspeed in wind tunnels and aboard aircraft in flight; they are also used to measure the flow of liquids (see flow meter).
