A soil sample has a porosity of 0.4. If the diffusion coefficient for a substance in the fluid is 1.0 cm²/s, calculate its effective diffusion coefficient using the Millington-Quirk equation.
💡 Hint: Remember to apply the Millington-Quirk formula correctly.
Discuss how increasing porosity in a material affects the transport of a pollutant over time.
💡 Hint: Consider the ease of moving through a denser versus a less dense medium.
