Challenge Problems
Push your limits with advanced challenges
You have a river contaminated with a DNAPL affecting the water quality downstream. If the concentration in the sediment is 20 mg/L and in the water is 5 mg/L, using a mass transfer coefficient of 0.1 cm/hr, estimate the flux into the water.
💡 Hint: Make sure to plug in your values carefully and use the correct units.
A study results in a correlation for evaporation from water stated as K = 0.025 * (vel^0.5). If the average wind speed is 10 m/s, calculate the mass transfer coefficient for evaporation.
💡 Hint: Remember to evaluate the units based on the provided correlation.
