A device invented by Henri Pitot (1695–1771) in 1732
and widely used in fluid dynamics for measuring fluid velocities. One open
end of a cylindrical tube points directly into the flowing stream, and the
other end is connected to a pressure-measuring device. This compares the
pitot-tube pressure with the static stream pressure, the difference being
a measure of the fluid velocity.
