A pitot tube is an instrument used to measure fluid flow velocity, particularly in aircraft to determine airspeed. It works by measuring the difference between the static pressure and the total pressure (also known as stagnation pressure). Think of it as a high-tech wind gauge for planes. 🌬️ This difference is then used to calculate the speed of the fluid—air in the case of airplanes. Proper functioning of the pitot tube is crucial for accurate airspeed readings, which are vital for safe flight. Malfunctions can lead to dangerous situations.
