Glycerol 85% was measured using a size IIa capillary viscometer. Calculate the kinematic viscosity based on the viscometer constant (see capillary viscometer method manual) and flow time values (see table below). The density of glycerol 85% is 1.226 g ∙ cm-3. Calculate the dynamic viscosity of Glycerol 85%. State the units for the calculated kinematic and dynamic viscosity!
