Challenge Problems
Push your limits with advanced challenges
A chemical spill of 200 liters occurs on a river. Estimate how the concentration in the water changes over time, given the following: initial concentration is 0 ppm, and kA is 0.5 for the dissolved chemical.
💡 Hint: Don't forget to keep track of your time intervals!
Consider a scenario where a pollutant evaporates from a surface. If the initial pollutant concentration is 50 mg/m³ and the mass transfer coefficient is 0.1 m/s, how long will it take to reduce to a concentration below 10 mg/m³?
💡 Hint: Reflect on the first-order decay processes we've discussed.
