Density, Viscosity, and Surface Tension of Sodium Carbonate + Sodium Bicarbonate Buffer Solutions in the Presence of Glycerine, Glucose, and Sucrose from 25 to 40 °C The density, viscosity, and surface tension of 0.5 M sodium carbonate + 0.5 M sodium bicarbonate buffer solutions in the presence...
Furthermore, by adding different percentages of glycerine, the liquid viscosity was varied and thus the effect of another governing parameter, Ohnesorge or Capillary number, could be identified. We have also added surfactant to change the surface tension of the test fluid, which create...
The measurement of dynamic surface tension of highly viscous liquids by the maximum bubble pressure method. Colloids Surf., A 1993, 75, 229-235.Fainermann, V.B., Makievski, A.V., and Miller, R., 1993, "The Measurement of Dynamic Surface Tensions of Highly Viscous Liquids by the ...
The centripetal acceleration of a rotating liquid film is tantamount to a centrifugal force, which tends to cause the liquid film to form rings around the circular cylinder to which it is attached. The stabilizing factors are surface tension and, presumably, viscosity. But it is shown in this...
The present invention relates to a method for the production of a urea fertilizer with elemental sulphur from sulphur in liquid stage and a liquid urea melt. The surface tension between the two phases of sulphur and urea are influenced in the liquid stage at temperatures above the melting points...
The bubbles in surface active agent solution remained spherical in much bigger size than those in pure water.Data on the terminal velocity of gas bubbles are shown in Fig. 6. Of spherical and ellipsoidal bubbles, the surface tension ... T Tadaki,S Maeda - 《Chemical Engineering》 被引量:...
As understood herein, ink-jet compatible inks have a viscosity of about 1 to about 45 centipoise, and a surface tension of about 15 to about 50 dynes/cm. In a pigmented ink, the average particle size is determined by the printhead channel, and is preferably less than about 50 microns, ...
Surfactants (also called surface active agents or wetting agents) are organic chemicals that reduce surface tension in water and other liquids. There are hundreds of compounds that can be used as surfactants. These compounds are usually classified by their ionic behavior in solutions: anionic, cation...
21. The apparatus of claim 13 wherein said fluid comprises glycerine. 22. The apparatus of claim 13 wherein said hose is contained in an enclosure. 23. An apparatus for detecting an acoustic signal of wavelength W and frequency F in drilling fluid comprising: a pipe containing the drill...
The surface tension of the surface skin of coatings produced in accordance with the present invention is so high, that other liquid oleo-resinous coatings placed on top of it, are unable to adhere and to form a coherent layer, so that they are actually repelled by the glazed surface, and...
