Challenge Problems
Push your limits with advanced challenges
A sediment column has a porosity of 0.45, and the retardation factor is calculated at 2.5. Calculate the effective diffusivity if the original diffusivity of the substance is known as 1.0 cm²/s.
💡 Hint: Focus on how retardation affects the effective rate.
Analyze how changes in bulk density could affect the effective diffusivity in a sediment analysis environment where porosity is altered.
💡 Hint: Consider what density means for the volume available.
