Challenge Problems

Push your limits with challenges.

Question 1

Given that a chemical has a concentration of 20 mg/L in water and 0.5 mg/L in the air, calculate the mass transfer flux if the liquid and gas coefficients are 5.0 m/s and 2.0 m/s respectively.

💡 Hint: Use the flux formula to account for individual mass transfer resistances.

Question 2

A factory discharges wastewater with a concentration of a pollutant at 50 mg/L into a river with a concentration of 2 mg/L. If the mass transfer coefficients are 10 m/s for water and 5 m/s for air, determine how quickly the pollutant will spread to the air.

💡 Hint: Remember to apply the resistance in the formula correctly.
