Exp.4 Determination the Viscosity of Liquids

Viscosity can be measured by timing the flow of a known volume of fluid from a viscosity measuring cup. The timings can be used in a formula to estimate the kinematic viscosity value … Oil Viscosity Index and Viscosity Temperature Relation Identify two reference oils whose kinematic viscosity at C coincides with the kinematic viscosity of the unknown oil (from the look-up chart of ASTM standard). Pick-up the kinematic viscosity of two identified reference oils at C In reference to illustration above, now a, b, and c are known.

## Apparent viscosity (sometimes denoted η) is the shear stress applied to a fluid divided by the shear rate ({\displaystyle \eta = {\frac {\tau } {\dot {\gamma }}}}).
