  • Difference Between Porosity and Permeability

    Oct 13, 2015· Main Difference – Porosity vs. Permeability. Porosity and permeability are both properties of rocks and soil. The main difference between porosity and permeability is that porosity is a measurement of space between rocks whereas permeability is a measurement of how easy it is for fluids to flow between rocks.. What is Porosity. Porosity measures how much space is between rocks.

  • Permeability (foundry sand) Wikipedia

    Permeability is a property of foundry sand with respect to how well the sand can vent, how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions.
