Question

What is the relationship between porosity and permeability?

Answer 1

Hint: The amount or percentage of pore space in a volume of soil is known as soil porosity. Porosity and Permeability are inversely associated, so if a soil has a larger proportion of Porosity, it will have a lower percentage of Permeability.

Complete answer:
The ability of a rock to hold a fluid is measured by its porosity. Permeability, on the other hand, is a measurement of the ease with which fluid can flow through a porous substance. In electrostatics, however, permeability refers to a material's ability to allow the development of magnetic lines of force or magnetic fields.
The qualities of porosity and permeability are linked in any rock or loose sediment. The number, size, and linkages of openings in the rock are all related. The porosity of a rock, in further detail, is a measure of its ability to hold a fluid. It is the open space in a rock divided by the entire rock volume in mathematics (solid and space). The ease with which a fluid can flow through a porous substance is measured by permeability. Even if a rock is extraordinarily porous, it will have little permeability if the pores are not connected. Similarly, a rock may have a few continuous fissures that allow fluid to flow freely, yet when porosity is measured, the rock does not appear to be extremely porous.

Note:
The quantity of pore space between particles in soil or rocks is referred to as porosity. Permeability uses this pore space to link the voids together, allowing water to move through. Porosity is more closely linked to water storage, whereas permeability is more closely linked to groundwater movement and flow.
