Aviation Guys do you really know use of these equipment in plane

Basically, a pitot tube is used in wind tunnel experiments and on airplanes to measure flow speed. It’s a slender tube that has two holes on it. The front hole is placed in the air stream to measure what’s called the stagnation pressure. The side hole measures the static pressure.

Pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 18th century and was modified to its modern form in the mid-19th century by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft, water speed of a boat, and to measure liquid, air and gas flow velocities in industrial applications. The pitot tube is used to measure the local flow velocity at a given point in the flow stream and not the average flow velocity in the pipe or conduit.
