Viscosity is determined by measuring the force ie. Frac 067 N s per square m 10 kg per cubic m 10kgpercubicm067N spersquarem. One poise 01 NSm 2.
Kinematic viscosity n 3 m 2 s.
Another application of shear viscosity models is Darcys law for multiphase flow. Torque required to turn the probe. The viscosity of the fluid is given by Hagen Poiseuilles formula ii Coaxial Cylinder Viscometer or Concentric Cylinder Viscometer. Flow characteristics of the GARDCOISO viscosity cups are accurately defined by mathematical formula relating them to the viscosity of standard oils which are traceable to the National Institute of Standards and Technology.
