In this work we present an analytical expression to accurately calculate the density of aqueous glycerol solutions. Viscosity of Aqueous Glycerine Solutions in Centipoises/mPa s Temperatur e (☌) Glycerine percent weight 0 10 20 30 40 50 60 70 80 90 100 0 (1) 1.792 1.308 1. Although the density of aqueous glycerol solutions has been measured precisely since more than a century, current models show a deviation from measured data of up to \(2\%\). ![]() ![]() In science, aqueous solutions of glycerol are commonly used for experimental investigations as their density can be adapted by changing the glycerol content in the solution. Glycerol is used in many applications of science and daily life as it is cheap and biologically non-invasive. The viscosity of water decreases smoothly from the freezing point while the density remains essentially constant except for the small maximum in density near 4☌. In cgs units the unit is called the centistoke. The kinematic viscosity is the dynamic viscosity divided by the density of the fluid. The unit centiPoise = 0.001 Pa s and is is sometimes written mPa s. These viscosities are at 20☌ except for the blood and blood plasma which are at body temperature, 37☌, and for steam which is at 100☌. 20☌ (66☏) Liquid Dynamic Kinematic Vapor Sound Density, Viscosity, p., Viscosity, v. The Poise is used in the table because of its more common usage. More commonly used is the dyne sec/cm 2 which is called Poise. The density value of experimental was an average of. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. The pycnometer filled with liquid was kept in the water bath for 20 min to accomplish thermal equilibrium. In this method the following are defined as mixed critical pressure as. Viscosity of Liquids and Gases Viscosity of Liquids and Gases Liquids To estimate the viscosity of the mixture with n component Hougen and Watson's method for pseudocritial properties is adapted.
