tension

 [ten´shun]
1. the act of stretching.
2. the condition of being stretched or strained; the degree to which something is stretched or strained.
3. the partial pressure of a component of a gas mixture or of a gas dissolved in a fluid, such as oxygen in blood.
5. mental, emotional, or nervous strain.
6. hostility between two or more individuals or groups.
arterial tension blood pressure within an artery.
carbon dioxide tension the partial pressure of carbon dioxide in the blood, noted as pCO2 in blood gas analysis. See also respiration.
electric tension electromotive force.
intraocular tension intraocular pressure.
surface tension tension or resistance that acts to preserve the integrity of a surface.
tissue tension a state of equilibrium between tissues and cells that prevents overaction of any part.

sur·face ten·sion (γ, σ),

the expression of intermolecular attraction at the surface of a liquid, in contact with air or another gas, a solid, or another immiscible liquid, tending to pull the molecules of the liquid inward from the surface; dimensional formula: mt-2.

sur·face ten·sion

(sŭr'făs ten'shŭn)
The expression of intermolecular attraction at the surface of a liquid, in contact with air or another gas, a solid, or another immiscible liquid, tending to pull the molecules of the liquid inward from the surface; dimensional formula: mt-2.

surface tension

A property of a liquid surface, arising from unbalanced molecular cohesive forces, in which the surface behaves as if it were covered by a thin elastic membrane under tension and tends to adopt a spherical shape.

Surface tension

The attraction of molecules in a fluid for each other.

The interfacial tension between PTT and PA6 is measured around 0.5 mN [m.sup.-1] by the acid-base approach, highlighting a thermodynamically favorable interaction between the components.
According to (3), the liquid-gas interfacial tension is inversely proportional to the solute diffusion coefficient, implying that the DC-induced promotion of solute diffusion coefficient obviously decreases the liquid-gas interfacial tension of liquid Ga-In-Sn alloy regardless of current polarity, which is in agreement with the calculated results.
Interfacial tension is 0.001 mN/m, quantity of flow Q is 2e - 10 [m.sup.3]/s, viscosity ratio is 0.5, We is 0.4, Re is 5e - 6, Ca is 0.6, and t is 0.4 s.
The greater oil recovery displayed by Si[O.sub.2] was probably due to its effectiveness to reduce interfacial tension and wettability alteration in porous media.
