Viscosity conversions are based on fluids with specific gravity of one. Check ASTM D 2161 "Standard Practice for Conversion of Kinematic Viscosity to Saybolt Universal Viscosity or to Saybolt Furol Viscosity"Ģ) Water at 68.4 o F (20.2 o C) has an absolute viscosity of one - 1 - centiPoise. This leads us to the fact that dynamic viscosity is a constant property, but kinematic viscosity is a derived property.Water - Absolute to Kinematic Viscosities Converter Absolute Viscosityġ) The Saybolt Universal SUS viscosity equivalent (SSU or SUS) to a given kinematic viscosity varies with the temperature at which the determination is made. Kinematic viscosity has units of diffusivity, (length) 2/s, which means that kinematic viscosity is sometimes known as diffusivity of momentum, dependent on thermal and mass diffusivity. In Newton’s Law of Viscosity equation, the proportionality constant is μ or dynamic viscosity. The ratio of shear stress to shear rate is defined as the viscosity. Newton’s Law of Viscosity states that shear stresses between parallel layers of fluid are proportional to the corresponding velocity gradients.
