capillarity

 [kap″ĭ-lar´ĭ-te]
the action by which the surface of a liquid where it is in contact with a solid, as in a capillary tube, is elevated or depressed.

cap·il·lar·i·ty

(kap'i-lar'i-tē),
The rise of liquids in narrow tubes or through the pores of a loose material, as a result of capillary action.

cap·il·lar·i·ty

(kap'i-lar'i-tē)
The rise of liquids in narrow tubes or through the pores of a loose material, as a result of capillary attraction.

capillarity

the action by which the surface of a liquid (usually water) is elevated when in contact with a solid surface by attraction of molecules between the liquid and solid surfaces. When the liquid is in a narrow container (e.g. a capillary tube) the level of water will rise considerably, but capillarity can also occur in such structures as soils, causing a rise in the water table. Capillarity has been suggested as the explanation of water ascent in XYLEM vessels in plants, but is not considered to exert a significant effect. Compare COHESION/TENSION HYPOTHESIS, ROOT PRESSURE.

cap·il·lar·i·ty

(kap'i-lar'i-tē)
The rise of liquids in narrow tubes or through the pores of a loose material, as a result of capillary action.

Values for the parameters of the bimodal water retention curves (Eqn 1) estimated for the different samplings dates, soils tillage treatments (conventional tillage, CT; reduced tillage, RT; no tillage, NT) and soil-wetting processes (waterlogging, WP; capillarity rise, CRP), and coefficient of determination ([R.sup.2]) for the best fit between the averaged measured and modelled water retention curves [[theta].sub.sat] and [[theta].sub.res] are the saturated and residual volumetric water content respectively; w is a weighting factor for the subcurves; [[alpha].sub.i] is the scale factor; [n.sub.i] is the pore-size distribution parameter.

One can also verify that the energy loss is dominated by the action of adhesion and capillarity forces, because the larger area between both curves is in the attractive region.
To simplify the above equation, we assume that the nanowire is a rod-like shape, although the cross section of the nanowire is a pentagon, (29) and the part of wet film for the area fraction estimation is perfectly flat and uniform, i.e., far from swollen edges due to the capillarity. In this case, the estimated area fraction becomes a function of the film thickness hw and the mass concentration of Ag NW [c.sub.AgNW].
In fact, the water movement has an important role in the accumulation of salt in the soil surface layer due to evaporation in the capillarity tubes.
