  2. Surface tension - Wikipedia

    en.wikipedia.org/wiki/Surface_tension

    Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.

  3. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Surface tension prevents the clip from submerging and the water from overflowing the glass edges. Temperature dependence of the surface tension of pure water. Water has an unusually high surface tension of 71.99 mN/m at 25 °C [64] which is caused by the strength of the hydrogen bonding between water molecules. [65] This allows insects to walk ...

  5. Eötvös rule - Wikipedia

    en.wikipedia.org/wiki/Eötvös_rule

    The surface tension is a linear function of the temperature. This assumption is approximately fulfilled for most known liquids. When plotting the surface tension versus the temperature a fairly straight line can be seen which has a surface tension of zero at the critical temperature.

  6. Morton number - Wikipedia

    en.wikipedia.org/wiki/Morton_number

    where g is the acceleration of gravity, is the viscosity of the surrounding fluid, the density of the surrounding fluid, the difference in density of the phases, and is the surface tension coefficient. For the case of a bubble with a negligible inner density the Morton number can be simplified to

  7. Szyszkowski equation - Wikipedia

    en.wikipedia.org/wiki/Szyszkowski_equation

    γ is surface tension of the mixture; γ 0 is surface tension of pure water; R is ideal gas constant 8.31 J/(mol*K) T is temperature in K; ω is cross-sectional area of the surfactant molecules at the surface; The surface tension of pure water is dependent on temperature. At room temperature (298 K), it is equal to 71.97 mN/m [4]

  8. Water potential - Wikipedia

    en.wikipedia.org/wiki/Water_potential

    Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension).

  9. Liquid entry pressure - Wikipedia

    en.wikipedia.org/wiki/Liquid_entry_pressure

    where is a pore geometry coefficient (= 1 for cylindrical pores and 0 < < 1 for non-cylindrical pores), [3] is the liquid surface tension, is the contact angle measured on the liquid side, where the liquid-vapor interface meets the membrane surface, and is the maximum pore size of the membrane.
