What does Fick's law state?
💡 Hint: Remember: Higher concentration differences mean greater flux.

Challenge Problems
Push your limits with advanced challenges
A river polluted by sewage shows a concentration of pollutant A at 5 mg/L. By applying the mass balance concept, how would you calculate the concentration at a downstream point 100m away if the mass transfer from sediments is estimated at 2 mg/L?
💡 Hint: Use the concept of mass balance for transfer rates.
Given that the diffusion coefficient of a substance is known to be 0.5 cm^2/s in water, calculate the flux if the concentration difference is 10 mg/m^3 over a distance of 0.1m.
💡 Hint: Remember to apply the negative sign for flux directionality.
