Challenge Problems
Push your limits with advanced challenges
A river has a DNAPL spill and a flux of 20 kg/m²/h is estimated. If the concentration in sediment is 100 mg/L and in water is 10 mg/L, calculate the mass transfer coefficient.
💡 Hint: Remember to convert units if necessary.
Discuss the approach you would take if the wind speed changes significantly while assessing evaporation coefficients from a lake.
💡 Hint: What happens to the mass transfer rate as wind speed increases?
