Membranes and Rivers
Set membrane thickness or concentration difference to hit a target flux, choose an effluent flow so the mixed river stays under a limit, and set the river speed so a dye reaches a gauge on time.

Theory and model assumptions
Set membrane thickness or concentration difference to hit a target flux, choose an effluent flow so the mixed river stays under a limit, and set the river speed so a dye reaches a gauge on time.
Teacher guidance
Poly chemical and environmental engineering: steady diffusion through membranes, complete mixing of an effluent and advection of a tracer (generic)
Expected time: 15–20 minutes.
