Sutherland's law viscosity
Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas, in most gases, viscosity increases with increasing temperature. This article discusses several models of this dependence, ranging from rigorous first-principles calculations for monatomic gases, to empirical correlations for liquids. Understanding the temperature dependence of viscosity is important in many applications, for in… SpletFirst, the viscosity coefficient is computed for each individual species n using Sutherland's law, as follows: μ n / μ 0 = ( T / T 0 ) 3/2 ( T 0 + S ) / ( T + S ) where T is the local static temperature, and μ 0 , T 0 , and S are constants read from …

SpletWhen a high viscosity sand suspension is used, the sand bank builds up slowly and extends well into the fracture because the settling rate of the sand is comparatively slow with respect to the low viscosity fluid (see Figure 3-16b).At completion, the proppant placement in the fracture occupies a greater percentage of the height and length of the fracture, …
