Relative Viscosity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Relative viscosity ( \(\eta_r\) ) 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
