Challenge Problems
Push your limits with advanced challenges
A waste tank initially has 500,000 kg of sludge with 20% moisture content. If 500 m³ of rainwater enters, calculate the final concentration of chemical A if it was initially 300 mg/kg in the dry weight.
💡 Hint: Break down the problem into parts. Determine initial mass and moisture before calculating.
Consider a scenario where the rainwater introduced has 100 mg of chemical A per liter. How does this impact the mass balance?
💡 Hint: Account for additional inputs when estimating final concentrations.
