Source: Reduced viscosity

In fluid dynamics, the reduced viscosity of a polymer is the ratio of the relative viscosity increment (

η

i

{\displaystyle \eta _{i}}

) to the mass concentration of the species of interest (c). It has units of volume per unit mass.
The reduced viscosity is given by:

η

i

c

{\displaystyle {\frac {\eta _{i}}{c}}}

where

η

i

{\displaystyle \eta _{i}}

is the relative viscosity increment given by

{\displaystyle \eta _{i}={\frac {\eta -\eta _{s}}{\eta _{s}}}}

(Where

η

s

{\displaystyle \eta _{s}}

is the viscosity of the solvent.)
