Kinematic Viscosity

 

 

Kinematic viscosity is the time required for a fixed amount of fluid or oil to flow through a capillary tube under the force of gravity.  Units of kinematic viscosity are stoke, centistoke (1/100 of a stoke) and Saybolt Universal Seconds (SUS). Saybolt Universal Seconds or Saybolt Universal Viscosity (SUV) is the time in seconds required for 60 cubic centimeters of a fluid to flow through the orifice of the standard Saybolt universal viscometer at a given temperature under specified conditions, usually per ASTM D 88.  Kinematic viscosity is also described as the quotient of the absolute viscosity in centipoises divided by the specific gravity of a fluid where both are measured at the same temperature.
