principle

Permeability refers to the ability of a porous material to allow fluid to pass through under a certain pressure difference.

It is a parameter that characterizes the ability of porous materials to conduct liquids. Its size is related to factors such as porosity, geometric shape of pores in the direction of liquid permeability, particle size, and arrangement direction, and is independent of the properties of the liquid moving in the medium. The permeability (k) is used to represent the magnitude of permeability.

The permeation velocity of a liquid with a dynamic viscosity coefficient of 1 in a medium when the pressure gradient is 1. Dimension is L2

The unit of permeability is the square of length, which is the same as the unit of area. But we call it Darcy (D), and the commonly used unit is milliDarcy (md).

formula

F = k (A /m l) (pi – po)

Among them:

L=thickness of test sample

Pi=inlet pressure

Po=export pressure

function
