What is mozilla firefox 40.039/7/2023 The uncertainties in dynamic viscosities are of the order of ☐.003 mPa.s. The flow time measurements were done at least three times so that each data reproducible to ☐.05 s was obtained, and the results were averaged. An electronic digital stop watch was used for the flow time measurements. The viscosities of pure liquids and solutions were measured by Ubbleohde viscometer at 298.15 K. The densities of all the pure liquids and their binary solutions were measured by Anton Paar densitometer (model No. 10 The purified liquids were stored in air tight bottles over 0.4 nm molecular sieves.Īll the binary mixtures were prepared by volume and were stored in stoppered bottles to minimize the error due to evaporation. These liquids were purified by standard method. The studied liquids used in the present study were of analytical grade and were supplied by S. Further, some excess parameters such as excess volume and excess viscosities have also been evaluated. These theories are tested for these studied binary mixtures using experimental data of viscosities. For binary and non-electrolytic solutions, vvarious theories have been developed such as Bingham, Kendall-Munroe, Arrhenius- Eyring, Katti and Chaudhari, Grunberg-Nissan etc. In the present work, densities and viscosities of binary mixtures of dimethyl sulphoxide with some alcohols such as methanol, ethanol, 1-propanol, iso-propanol, 1-butanol, iso-butanol, ter-butanol have been measured at 298.15 K. 1 The determination of viscosity of liquid mixtures are of interest in chemical industries and chemical engineering involving fluid transportation, process design, pump operations, heat exchange, mixing agitation etc. ![]() Viscosity is an important transport property. ![]() Transport properties of binary solution have proven to be a useful tool in elucidating the interactions occurring in solutions.
