===Pitot tube===
{{Main|Pitot tube}}
A [[pitot tube]] is used to measure fluid flow velocity. The tube is pointed into the flow and the difference between the [[stagnation pressure]] at the tip of the probe and the [[static pressure]] at its side is measured, yielding the dynamic pressure from which the fluid velocity is calculated using [[Bernoulli's equation]]. A volumetric rate of flow may be determined by measuring the velocity at different points in the flow and generating the velocity profile.
