A static tube is a type of probe that is used in fluid mechanics to measure the pressure of a fluid. Sometimes, however, this term may not be suitable for use in certain contexts. In such cases, synonyms for static tube may be used. Some of the synonyms that can be used in place of static tube are pressure probe, Pitot tube, and stagnation tube. Pressure probe is commonly used in the aerospace industry to measure pressure. Pitot tube is often used in aviation and measures both static and dynamic pressure. Finally, a stagnation tube is used in hydraulics to measure fluid velocity. These synonyms help to expand and clarify the use of the static tube in various contexts.
