Surf ace tension

The Weber-Reynolds number (Re/We) is defined as the ratio of surf ace tension of a bubble to viscous shear on the bubble surface due to bubble motion ... 

Effect of physical properties Physical properties of liquid metals that have significant effects on CHF values are thermal conductivity, latent heat of vaporization, and surf ace tension. 

The heat of vaporization of H2O is about 1.5 times that of CCI4. Which liquid should have the larger surf ace tension ... 

In Eq. (1), 1 is the time, q is the viscosity of the continuous phase, is the radius of the disk, and AP is the pressure difference causing the flow. The driving force AP is a net result of the suction pressure in the adjacent Plateau border channels and the disjoining pressure (17) in the films, and is given by AP = a jr — 77, where a is the surf ace tension and is the radius of curvature of the Plateau border channels. The coefficient Cf is a correction factor that accounts for the mobility of the film surfaces and is given by [42] ... 

To prepare stable PVC latexes by emulsion polymerization of VC, considerable attention must be paid to the choice of a proper emulsifier. The emulsifier greatly affects the reaction kinetics and the physico-chemical and colloidal properties of the final polymer product and/or the dispersion [98]. The choice of the proper emulsifier is a complex problem because of its manifold functions, e.g. the surf ace tension of the aqueous solution, emulsification or solubilization of oil-soluble monomers or additives, and the protection of latex particles against flocculation [99].
