High viscosity liquids5/16/2023 ![]() Some of the most common methods are as follows: 1. There are several different methods to measure both dynamic and kinematic viscosity. In the centistoke, one cSt equals 10 -6 m 2/s = 1 mm 2/s. Where the viscosity value in Stoke is too large, the smaller unit centistoke (cSt) is often used in its place. Another unit of measurement for this property is Stoke (St), where one St equals 10 -4 m 2/s equals 1 cm 2/s. The SI unit for dynamic viscosity is m 2/s. μ = absolute or dynamic viscosity (N s/m 2).Mathematically, kinematic viscosity can be expressed as: This viscosity is especially useful in describing Newtonian fluids. It reflects a fluid’s resistance to shear flow under the influence of gravity, i.e., shear flow due to the fluid’s own weight. Kinematic viscosity is simply the ratio of the dynamic viscosity to the fluid's density. In the centipoise unit, one cP equals 0.01P, 0.001 N s/m 2 or 0.001 Pa s. For this reason, centipoise (cP) unit is often used in its place. The poise unit can sometimes be too large for practical purposes. Another unit of measurement for dynamic viscosity is poise (p), where one poise equals one-teneth N s/m 2 or 1/10 Pa s. The SI unit for dynamic viscosity is N s/m 2 or the Pascal-second (Pa s). μ = dynamic viscosity of fluid (N s/m 2).Mathematically, dynamic viscosity can be expressed as: Temperature and Pressure - Free online calculator - figures and tables with viscosity of water at temperatures ranging 0 to 360☌ (32 to 675☏) - Imperial and SI Units.Dynamic viscosity is especially useful when describing non-Newtonian fluids.
