Reduced viscosity

Template:Multiple issues In fluid dynamics, the reduced viscosity of a polymer is the ratio of the relative viscosity increment (${\eta }_i$) to the mass concentration of the species of interest (c). It has units of volume per unit mass.

The reduced viscosity is given by:

$\frac{{\eta }_i}{c}$

where ${\eta }_i$ is the relative viscosity increment given by ${\eta }_i=\frac{\eta -{\eta }_s}{{\eta }_s}$ (Where ${\eta }_s$ is the viscosity of the solvent.)Template:R
