Viscosity of Liquid
Definition
Viscosity of liquid is the resistance to the movement of liquid. In short, it is the extent of liquid adhesiveness due to the intermolecular force
Estimation Method
MolInstincts
Property values are estimated by the combination of fundamental thermodynamic theories, modern modeling approaches, e.g., SVRC (Scaled Variable Reduced Coordinates), QSPR (quantitative structure-property relationships) methods, and ANN (Artificial Neural Network) with over fitting prevention algorithm, utilizing the quantum chemical calculations results and molecular descriptors. The estimated value is finally determined after manual inspection.
