The following table illustrates the range of viscosity values observed in common substances. (1) can be rearranged to express Dynamic viscosity as, = / (1b), In the SI system the dynamic viscosity units are N s/m2, Pa s or kg/(m s) - where, Dynamic viscosity may also be expressed in the metric CGS (centimeter-gram-second) system as g/(cm s), dyne s/cm2 or poise (p) where, For practical use the Poise is normally too large and the unit is therefore often divided by 100 - into the smaller unitcentipoise (cP) - where. A Thixotropic fluid has a time-dependent structure. To be specific, viscosity defines a fluid's resistance to flow. Area = m. Relative or Specific viscosity is the ratio of dynamic viscosity of any fluid to the dynamic viscosity of water at 20C. 2 A rotary viscometer is a popular instrument, used to measure dynamic viscosity. The kinematic viscosity tells how fast the fluid moves when a certain force is applied, while dynamic viscosity gives you information on the force needed to make the fluid flow at a certain rate.
