Challenge Problems
Push your limits with advanced challenges
Given that a tank contains 600,000 kg of sludge with 250 mg of contaminant A per kg, if 800 m³ of rainwater is added, calculate how the concentration of A changes after mixing.
💡 Hint: Set up your mass balance based on the initial and final states.
If the rainwater is found to contain 5 mg/kg of contaminant B, how would you adjust your calculations for total contaminant contributions in the aqueous phase?
💡 Hint: Remember that all sources and outputs need to be accounted for.
