It is a potential developed when a liquid is forced through a porous membrane or capillary. The oppositely charged layers of electrical double layer are separated when liquid passes through membrane. It results in the development of potential between the two sides of membrane.
Thus, streaming potential is exactly reverse of electro osmosis.
| In electro osmosis flow of liquid takes place due to applied potential | In streaming potential, the potential is developed due to the flow of liquid. |
|---|
It is possible to measure the streaming potential by using reversible electrodes like calomel electrodes. Such electrodes are kept at two ends of the membrane and potential difference arising due to passage of water or liquid is measured.
Streaming potential (S) and zeta potential \((\xi)\) are related by the equation. $$ \xi = \frac { P\pi \eta kS }{ D } $$ Where, \(\eta\) = viscosity of the medium,
k = specific conductance of the liquid,
P = a pressure applied to cause the flow
D = dielectric constant of the medium.

Don’t want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works.

For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to
