Challenge Problems

Push your limits with challenges.

Question 1

Calculate the concentration after 2 hours given a continuous spill of 10 kg/hr over a lake of 2000 m³, with a mass transfer coefficient of 0.5.

💡 Hint: Consider the continuous nature of the spill.

Question 2

In a model where winds are dispersing a pollutant, derive a formula to project concentration change over time accounting for wind speed and mass transfer coefficient.

💡 Hint: Wind speed will influence the rate - remember to incorporate it into your equations.
