Relative Viscosity

Relative viscosity, abbreviated \(\eta_r\), is the ratio of the viscosity of a solution to the viscosity of a solution used.

 

Relative Viscosity formula

\(\large{ \eta_r = \frac {\eta} {\eta_s}  }\)

Where:

\(\large{ \eta_r }\)  (Greek symbol eta) = relative viscosity

\(\large{ \eta }\)  (Greek symbol eta) = viscosity of a solution

\(\large{ \eta_s }\)  (Greek symbol eta) = viscosity of a solution used
