Dynamic viscosity ( \(\mu\) (Greek symbol mu) ) also called "absolute viscosity" of "simple viscosity". The basic unit of absolute viscosity is the "poise". The most common unit for expressing absolute viscosity is the "centipoise" (1/100 of a poise).
The value of dynamic viscosity is measured by placing two plates together with a fluid betweeen them. One plate is introduced to a known shear stress. The plate will move with a give velocity. The velocity and shear stress are combined to determine the dynamic viscosity.
