  • 100 equally spaced hues around circle.

  • Brightness: Value from 0 for black to 10 for white

Porosity Vs. Permeability

These are two distinct physical properties of solids.

  • Porosity:

    • Measure of how much of a rock is open space.

    • This space can be between grains or within cracks or cavities of the rock.

    • Refers to the extent to which tiny pores or spaces exist within the solid.

  • Permeability:

    • Measure of the ease with which a fluid can move through a porous rock.

    • Refers to the ability of a mass of solid to permit or restrain the passage of fluids.

    • That is gases or liquids, through itself.
