A new setup for speed of sound measurements and experimental data for nanofluids Al2O3 or Ag with water or ethylene glycol
(Elsevier B.V., 2023)
The speed of sound of four different nanofluids consisting of Ag or Al2O3 nanoparticles and water or ethylene glycol base fluid is measured in the temperature range (298.15–343.15) K and at atmospheric pressure. One aim ...
Isopiestic determination of osmotic coefficients in the ionic strength range Im = (0.9670–2.2160) mol⋅kg−1 and activity coefficients determined by electromotive force measurements in the range Im = (0.0897–1.0054) mol⋅kg−1 of the {yKCl + (1 – y) K2HPO4}(aq) system at T = 298.15 K
(Elsevier B.V., 2022)
The mean activity coefficients of KCl in the ternary system {y KCl + (1 – y) K2HPO4}(aq) were experimentally determined at T = (298.15 ± 0.01) K by the electromotive force measurement (EMF method) using the cell of the ...
Free volume theory and extended mixing rule implementation for estimation of liquid viscosity of flue gas desulphurization candidate solvents
(Journal of Molecular LiquidsJournal of Molecular Liquids, 2022)
The free volume theory model was used to estimate viscosity of eight pure substances and their twenty-three binary mixtures. The selected viscosity data included compounds such as alcohol, ether, lactam, amine and polymer, ...
