Challenge Problems
Push your limits with advanced challenges
A chemical is spilled into a lake with a known area and initial concentration. Calculate how long it will take for the concentration in the lake to drop to half of its initial value, using appropriate mass transfer coefficients.
💡 Hint: This is a first-order decay problem; remember to apply ln calculations.
Model the dispersion of a volatile chemical from a spill on a road. Consider factors like wind speed, temperature, and area for evaporation.
💡 Hint: Consider how these parameters interact dynamically over the time frame.
