Permeability depends on membrane solubility and the presence of specific integral transport proteins.
Other factors such as pressure, concentration, and temperature of the molecules or solutes on either side, as well as the size of the molecules can also affect permeability.

rate of diffusion = (concentration gradient x permeability of molecule x total surface area) / (molecular weight of molecule x thickness of membrane)

What is the permeability of silicon?

How does the permeability of soil and rocks affect the flow of groundwater?
Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
How can man increase porosity and permeability in oil wells?
There is not feasible way to change the overall porosity and permeability in an oil field. However, it is possible in many cases to improve the porosity and permeability within the near wellbore region, where the change in pressure is the greatest. Injecting acid into a well, may slightlyincrease the porosity but sigmificantly improve the permeability, as it creates larger flow paths (also called worm holes) through the formation. Hydraulic fracturing will also stimulate a well, although the formation's permeability and porosity is unchanges. It makes it easier for oil to flow into the well, so its effect in the long run, is the same as if the near well bore region had higher permeability. Low permeability formations often produced by horizontal wells, which is similar to hydraulic fracturing- it is easier for the oil to flow to the well.
Changes in permeability?
Receptor protein is coupled with an ion channel
What is the magnetic permeability values of En8 steel and iron powder?
what is magnetic ppermeability of EN8
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
What is the ability of a cell membrane to allow material to pass through it called?
permeability
Does silt have high permeability?
Silt has neither high or low permeability. It has moderate permeability. :) !
Unit of relative permeability?
Relative permeability is dimensionless
What is permeability value of germanium?
16.0 is the value of permeability
What are facts about permeability?
Changes in permeability are changes in the number of compounds that can pass through a membrane. The presence of certain chemicals or radiation can change the permeability of a membrane.
What is the permeability of coars and fine sand?
The permeability of coarse sand is 1.89mL/s and the permeability of fine sand is 0.54mL/s.
What is the permeability of No. 8 gravel No. 67 limstone No. 8 limestone No. 57 stone and limestone sand?
The gravels will be very fast. The permability of the sand will depend on how clean it is. As more material passes the No. 200 sieve, permeability will rapidly decrease. At 10 to 15 percent, ponding will easily occur.
How does porosity and permeability interact?
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
Which of the following is a measure of a materials ability to transmit fluids through interconnected pore spaces capacity competence or permeability?
permeability
Permeability of a nonmagnetic medium is..?
permeability of nonmagnetic medium equal μο
What is soil permeability?
soil permeability is the amount of water soil can hold
