Static Tube

A static tube, also known as a pitot-static tube, is a device used to measure the static pressure and dynamic pressure of a fluid flow. It is commonly used in aerodynamics and fluid mechanics to determine the velocity of an aircraft or fluid flow.

The static tube consists of two tubes: a pitot tube and a static tube. The pitot tube is designed to measure the dynamic pressure, which is the pressure exerted by the fluid due to its motion. It has a small opening facing the flow, allowing the fluid to enter and exert pressure on the tube.

The static tube, on the other hand, is used to measure the static pressure, which is the pressure exerted by the fluid when it is at rest. It has multiple small openings along its length, allowing the fluid to enter and exert pressure on the tube.

By comparing the dynamic pressure measured by the pitot tube with the static pressure measured by the static tube, the velocity of the fluid flow can be determined using Bernoulli's equation. This information is crucial in various applications, such as aircraft speed measurement, wind tunnel testing, and fluid flow analysis.

Overall, the static tube is a valuable tool for measuring fluid flow parameters and is widely used in engineering and scientific research.
