Absolute Viscosity is sometimes referred to as Dynamic 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). 1 cp = 6.72 x 10-4 lbm/ft-sec
Absolute viscosity is commonly referred to by the Greek symbol mu (
). The SI unit of absolute viscosity is the pascal-second (Pa·s), which is identical to 1 kg m-1s-1</tex>. The value of absolute 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 absolute viscosity.
