Sphere in water
Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube. Electronic sensing can be used for opaque fluids. Knowing the terminal velocit… Web5. mar 2024 · It should make sense to you that towing a sphere at velocity U through a still fluid by exerting a constant force F D on it is equivalent to passing a steady and uniform …
