(redirected fromCapillary rise) Thesaurus Medical Encyclopedia capillary action n. The interaction between contacting surfaces of a liquid and a solid that distorts the liquid surface from a planar shape and causes the liquid to rise or fall in a narrow tube. ...
where h is the maximum capillary rise (cm); [gamma] is the surface tension of ethyl alcohol (dyne/cm); [alpha] is the soil contact angle assumed to be zero for ethyl alcohol; [rho] is the density of ethyl alcohol (g/[cm.sup.3]); and G is the acceleration due to gravity (cm/...
To explain and predict all rise heights and volumes with quantitative accuracy, we present the Dual-Rise model that is valid for general roughness, liquids, and surface wettabilities. Capillary rise is a process whereby a liquid spontaneously rises against gravity within a narrow space due to ...
The rise or fall of the surface of a liquid within a very narrow tube due to a difference in cohesive force within the molecules of liquid and the adhesive force between the liquid and the wall of the tube is known as capillary action....
Figure 2.50.Capillary rise is inversely proportional to the capillary diameter. Historically, many scientists have investigated this phenomenon, fromLeonardo da Vinci, to Hauksbee, and Jurin. This property is now referred to as Jurin's law. ...
We report experimental work on capillary rise of a liquid in a cell formed by parallel plates, one of which is flexible. We show that above a critical width, the cell collapses under the negative capillary pressure in the liquid. This collapse allows the liquid to rise virtually without limit...
.Capillary rarefactionhas been found to be present before and after the development of HT[2]. Candidate mechanisms responsible for this phenomenon include (a) unsatisfactory embryological development, (b) lack ofangiogenesis, and (c) collapse of existing capillaries (potentially reversible) due to ...
The capillary process coexists with gravity flow within leaching heap due to the dual-porosity structure. Capillary rise is responsible for the mineral dissolution in fine particle zones and interior coarse rock. The effect of particle size and heap porosity on the capillary process was investigated...
