Surface-tension and Surface-viscosity

Density, Viscosity and Surface Tension of Whey Protein Concentrate Solutions

We have determined the density, rheological behavior and surface tension of whey protein concentrate (WPC) solutions. Densities (r) were measured at concentrations of 0.05–0.40 w/w at temperatures of 20–35C. The results were expressed as a function of temperature and mass fraction (w). This function fit the data with deviations of less than 0.4%. Apparent viscosities (ha) for WPC solutions with...

Viscosity, resistivity and surface tension measurements of Fe,O, ferrofluid

The viscosity n of Fe,O, ferrofluid at volume concentrations in the range t = 0.0-0.013 are measured. The corresponding range of values of q is 1.6-1.8 cp. A linear relationship exists between the relative viscosity and the concentration of the fluid. Measurements of relative resistivity of Fe,O, ferrofluid at various concentrations (E = 0.00526-0.0526) are also reported. The relative resistivi...

synthesis of a special enamel for nickel-chrome resistor and characterizing the viscosity and surface tension

in the present work, attempts have been made to find appropriate coating by testing different compounds. results showed that the optimum enamel is a compound with 1 wt.% cobalt oxide, 3 wt.% chromium oxide (in addition to hundred percent) with the firing temperature of 840 ˚c. constants of vft equation were determined by examination of melting behavior of the optimum enamel and measurement of t...

Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

Density and Temperature Dependencies of Liquid Surface Tension

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
