WebApr 14, 2024 · The rising velocity of an air bubble in a non-Newtonian shear-thinning fluid at low Reynolds numbers is generally similar to the Newtonian case given by Stokes’ law. However, when the shear-thinning fluid is subject to mechanical oscillations, the rising velocity could significantly increase. emoko electric scooterStokes' 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 … See more In 1851, George Gabriel Stokes derived an expression, now known as Stokes' law, for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. Stokes' law is … See more The force of viscosity on a small sphere moving through a viscous fluid is given by: $${\displaystyle F_{\rm {d}}=6\pi \mu Rv}$$ See more Although the liquid is static and the sphere is moving with a certain velocity, with respect to the frame of sphere, the sphere is at rest and liquid is flowing in the opposite direction to … See more • Batchelor, G.K.
