An expression for the viscosity of liquid metals has been derived using a theoretical model based on the theory of liquids. The equation is expressed in terms of fundamental physical parameters such as the pair distribution function and the time-averaged interatomic frequency. The equation ...
A semi-theoretical model based on the classical Eyring's mixture viscosity equation and the Wilson activity coefficient equation is presented for correlating the viscosity of ionic liquids with solvent systems. The accuracy of the proposed model was verified by comparing calculated and experimental ...

When the relaxation time of securities density waves τ0 and that of production waves τM are shorter than their respective periods; q0τ0,q0τM<1 and the wave number q is smaller than a reciprocal worker distance K∼2π/a;aq<1, diffusivity D and viscosity ηλ appear, respectively,...
We propose an empirical equation that relates the shear viscosity of shear thickening fluid with a relative free volume. The proposed free volume-based equation is then utilised to develop a shear stress-dependent rheological equation and shear rate-dependent rheological equation for shear thickening ...

This teapot problem is a classic didactic problem that has been used for years in the classroom. The set of equations demonstrates relative viscosity of a fluid, the flow of a jet of fluid, al queda in a closed pipe, and the shape of a liquid surface. Areas commonly found in high-tech...
The effect of T on the kinematic viscosity of liquid is described by means of the Arrhenius equation (1) which describes the exponential decrease of kinematic viscosity versus T [8,9,10]: Kinematic viscosity of linseed oil, almond oil and diesel fuel The reaction rate/temperature relationship ...
bitumen - diluent mixture viscosityA new method is presented for the correlation and prediction of the effect of temperature on viscosity of liquid hydrocarbons and their mixtures. A one-parameter viscosity-temperature equation is described that has been validated with data for approximately 360 pure ...
