Newton proposed that the resistance to flow caused by viscosity is proportional to the velocity at which the parts of the fluid are being separated from one another because of the flow. Although Newton's law of viscosity is an empirical idealization, many fluids, such as low-molecular-weight ...
而(U/L)就是剪切变形速率(rate of shear deformation)。同样写成微分形式: \tau = \mu \frac{\Delta u}{\Delta y} \\上式说明如果剪切力不变,如果流体越粘,那么移动的距离越小。比如清水粘性很小,甘油粘度很大。这就是牛顿粘性定律(Newton`s Law of Viscosity)。牛顿做实验的那种流体,粘度可以看做是常数...

Stokes’ Law In class we have talked about the efficiency of air, water and ice to transport sediment. The main difference of the three transport media is their density D and viscosity :. Air has both, the lowest density and viscosity and is the least efficient transport medium. Ice, on ...
fluid at specific velocity. This law willform the basis of this laboratory investigation.Stokes' Law is written as,VdFd6where Fdis the drag force of the fluid on a sphere,mis the fluid viscosity, V is thevelocity of the sphere relative to the fluid, and d is the diameter of the sphere...
Stokes’ Law n(1) The mathematical equation derived by G. G. Stokes which relates the velocity of fall v of a spherical body under gravity g through a fluid medium to the radius r of the body, to the viscosityηof the medium and to the difference between the density of the solid ...
