  • Kinematic viscosity is the measure of resistance to flow with gravitation under its own mass force. This is normally reported in the units of centistokes(cst) or mm2 /sec.

  • Dynamic viscosity is the measure of resistance to flow with an induced shear stress or at a known rate of shear. This is determined from the equation of Shear Stress (Pascals - Pa) divided by Rate of Shear (inverse seconds - s-1 ). The unit of Dynamic viscosity is either Centipose (cps) or mPa s.
