Challenge Problems
Push your limits with advanced challenges
A chemical spill occurs in a river where flow velocity is measured at 2 m/s. If diffusion coefficient for the pollutant in water is 1 x 10^-5 m^2/s, calculate the effective transport mechanism when both processes co-exist.
💡 Hint: Compare coefficients of both processes.
You are tasked with modeling the pollutant transport in a groundwater system. How does the porosity of the soil impact both advection and diffusion?
💡 Hint: Consider how fluid can move through water-saturated systems.
