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. Related categories
