![]() ![]() While this paper is addressed, principally, to fluid dynamicists these results should be of interest to physicists studying the liquid state and physical chemists interested in mixtures. In the area of products for personal use it is clear, odorless and recognized as safe. On the other hand, fluids that take time to flow, like honey and glycerol, have high viscosities. But over and above its chemical combinations, pure glycerine offers the formulator a liquid with a for- tuitous balance of physical proper- ties, brand, viscous, stable, hygro- scopic and widely compatible. This correlation can now be used at a given temperature to tailor make a mixture of prescribed kinematic viscosity. Water has a low viscosity since water can flow readily. The constants a, b and c are tabulated in the paper as functions of temperature. It is shown that all the data can be reasonably represented by the empirical correlation (ln ν m - ln ν w)/(ln ν g - ln ν w) = x g, where ν w, ν g and ν m are the kinematic viscosities of water, glycerol and the mixture respectively and x g is the mass fraction of glycerol in the mixture. All liquids appear resistance to flow change from liquid to another, the water faster flow than glycerin, subsequently the viscosity of water less than glycerin. Abstract An empirical formula is proposed for the calculation of the viscosity of glycerol-water mixture for mass concentrations in the range of 0-100 and. Apart from comprehensiveness and comparative accuracy the present measurements expose serious errors in the limited data that were earlier available on such mixtures. The measurements were made by using a series of Ubbelohde viscometers. ![]() It is defined as the internal frictional resistance of a liquid to the application of a pressure or a shearing stress. Please, determine the type of fluid flow.

We have measured the kinematic viscosity of glycerol-water mixtures, for glycerol mass fractions ranging from 0 to 1, in the temperature range 10-50 degrees C. Velocity, density and dynamic viscosity of glycerin are 3.6 m/s, 1258 kg/m and 0.96 kg.m-1.1, respectively. ![]()
