Şuppose you have a wind speed gauge like the pitot tube shown in figure below. By what factor must wind speed increase to double the value of h in the manometer? Is this independent of the moving fluid and the fluid in the manometer? V, = 0 Figure caption: Meașurement of fluid speed bạsed on Bernoulli's principle. This type of velocity measuring device is a Prandtl tube, also known as a pitot tube. Is this independent of the moving fluid and the fluid in the manometer? O Yes

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
