Challenge Problems

Push your limits with challenges.

Question 1

Given the bulk concentration of a pollutant in a lake is 5 mg/L and the equilibrium concentration in air is 0.1 mg/L, calculate the mass transfer flux if the mass transfer coefficients for air and water are 0.01 and 0.1 m/s respectively.

💡 Hint: Make sure to differentiate between bulk and equilibrium concentrations.

Question 2

Design an experiment to measure the mass transfer coefficient for a gas dissolving in a liquid. Detail the necessary materials and the procedure.

💡 Hint: Remember to account for temperature and pressure changes during the experiment.
