A molecule whose Stokes radius approaches or exceeds the pore radius does not enter the gel and is said to be excluded
This scented skin soap can clear and refine pore openings completely, which makes you feel comfortable.
Fractures also may BE quite large and contribute substantially to the volume of pore openings in the rock.
They are also easy to fabricate and can BE produced with a wide range of pore size cutoffs for ultrafiltration.
Under extreme conditions of rapid Coke forming materials, pore mouth blockage can occur
F a pore gets blocked but stays open, the top surFace can darken and you are leFt with a blackhead.
The water squeezed out of the pore space, along with the drops of oil and GAS, moves toward high zones with lower pressure.
In the following derivation, instead of using pore velocity it is advantageous to use seepage or Darcian velocity
The configuration of the pore space is different from that which would be obtained from the packing of uniform spheres
In fact, two or more systems of pore openIngs may occur In such rocks.
