Challenge Problems
Push your limits with advanced challenges
A tank initially contains 600,000 kg of wet sludge with a moisture content of 0.4. If rainwater adds another 800,000 liters, calculate the new concentration of Chemical A if its initial mass was 250 mg/kg dry solid. How does this impact the mass balance?
💡 Hint: Don't forget to consider the density of water and convert volumes to masses accordingly!
Discuss how the chemistry of rainwater could alter the situation if it contains pollutants, and what analytical steps might be required to fully understand its impact on the sludge’s mass balance.
💡 Hint: Think about the consequences of polluted rainwater on environmental evaluations.
