Pitot tube

Pitot tube
/pee"toh, pee toh"/
(often l.c.) an instrument for measuring fluid velocity, consisting of a narrow tube, one end of which is open and faces upstream, the other end being connected to a manometer.
[1880-85; named after Henri Pitot (1695-1771), French physicist, who invented it]

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).
