The shearing stress necessary to induce a unit velocity flow gradient in a material. 2, record 1, English, - viscosity%20coefficient
Record number: 1, Textual support number: 1 OBS
In actual measurement, the viscosity coefficient of a material is obtained from the ratio of shearing stress to shearing rate. This assumes the ratio to be constant and independent of the shearing stress, a condition which is satisfied only by Newtonian fluids. Consequently, in all other cases, values obtained are apparent and represent one point of the flow curve. In the CGS system, the viscosity coefficient is expressed in poises, i.e. in dyne seconds per square centimetre, and in the International System of units in pascal seconds. 2, record 1, English, - viscosity%20coefficient

Dans la mesure réelle, le coefficient de viscosité d'une matière est obtenu par le rapport de la contrainte de cisaillement à la vitesse de cisaillement. Cela présume que le rapport est constant et indépendant de la contrainte de cisaillement, condition qui est satisfaite seulement par les liquides newtoniens. En conséquence, dans tous les autres cas, les valeurs obtenues sont apparentes et représentent un point de la courbe de fluidité. Dans le système CGS, le coefficient de viscosité est exprimé en poises, c'est-à-dire en dynes secondes par centimètre carré, et dans le Système international d'unités en pascals secondes. 2, record 1, French, - coefficient%20de%20viscosit%C3%A9

For many fluids the tangential, or shearing stress that causes flow is directly proportional to the rate of shear strain, or rate of deformation, that results. In other words, the shear stress divided by the rate of shear strain is constant for a given fluid at a fixed temperature. This constant is called the dynamic or absolute, viscosity and often simply the viscosity. 2, record 5, English, - dynamic%20viscosity
