Pitot Tube

Pitot Tube is a device used for measuring the velocity of flow at any point in a pipe or a channel. The Pitot tube was invented by the French Engineer Henri Pitot.

The principle of Pitot tube is based on the Bernoulli's equation, where each term can be interpreted as a form of pressure. If the velocity of flow at a point becomes zero, the pressure there is increased due to the conversion of kinetic energy into pressure energy.

The pitot tube is robust and simple to use. In its simplest form, it consists of a glass tube bent at right angles.
