Explain three advantages of pitot startic tube?

1. Accurate measurement: The pitot-static tube provides accurate measurement of fluid velocity and pressure. It is designed to measure both the dynamic pressure (velocity pressure) and the static pressure of a fluid flow. By measuring these two parameters, the tube can accurately determine the fluid's velocity, which is crucial in various applications such as aircraft speed measurement, flow rate measurement in pipes, and wind tunnel testing.

2. Versatility: Pitot-static tubes can be used in a wide range of applications and environments. They are commonly used in aviation for airspeed measurement, where they are mounted on the aircraft's nose or wings. They are also used in fluid mechanics experiments, industrial flow measurement, and meteorology. The tubes can be made from various materials such as stainless steel, aluminum, or plastic, making them suitable for different fluid types and operating conditions.

3. Simple design and low cost: Pitot-static tubes have a relatively simple design, consisting of a tube with two openings - one facing the fluid flow (the pitot opening) and the other perpendicular to the flow (the static opening). This simplicity makes them easy to manufacture and maintain, resulting in lower production costs compared to other flow measurement devices. Additionally, their simple design means they have fewer components that can fail or require calibration, reducing the overall cost of ownership.
