The other (written by A.V.) takes theĪ python version has now also been written by Matthew Partridge at Cranfield University. One takes volume fraction of glycerine as input. Further refinements from Andreas Volk to density of pure water, and the temperature-dependence of the contraction of the mixture. In both cases the fit was chosen to match data from Gregory (table 3 and 7) Andreas Volk pointed out that the density calculation can be made more accurate by (i) accounting for the volume contraction of the mixture (ii) adjusting the fit for the density of pure glycerine as a function of temperature. The dynamic viscosity calculator provides the density and the viscosity of water at 20 c as follow: Dynamic viscosity 1.0016 mPa.s. Thanks to Paul Debue for pointing this out. The mixture should use the glycerine fraction by VOLUME and not by mass. Density calculation has been changed: equation 25 in Cheng's paper to compute the density of I'd recommend reading the latter paper first. Kähler (2018) Experiments in Fluids 59 75. ![]() Its unit of measure is centistokes (cSt) which in SI units is mm2/s, 1cSt 1 mm2/s. the kinematic viscosity of water at 20C of 1.0034 mm2/s (internationally agreed value in accordance with ISO/TR 3666-1998, and subject to ITS 90). 47 3285-3288, with a number of adjustments (see below), which are described in Volk and Thus, it has a higher viscosity than water. 1 mm/s 3 600 mm/h mm/s>mm/h mm/h>mm/s What is mm/h. 1 mm/s 60 mm/min mm/s>mm/min mm/min>mm/s What is mm/min. What is kinematic viscosity Instant conversions Conversion tables. The calculation is based on the parameterisation in Cheng (2008) Ind. A square millimeter per second (mm/s) is a derived metric SI (System International) measurement unit of kinematic viscosity. Calculate density and viscosity of glycerol/water mixturesĭynamic viscosity of mixture is :
