Concentration, units & dimensions Learning Objectives: Define Environmental
Concentration, units & dimensions Learning Objectives: Define Environmental Fluid Mechanics (EFM) List and define three types of concentration measures List the dimensions of concentration, mass fraction, and the diffusion coefficient Convert concentration measures among various units (i.e. mg/l to mol/l) Motivational Question: How do you quantify the amount of a
chemical dispersed in the environment? Examples of Environmental Fluid Mechanics Projects OCEN 489 and 689 Scott A. Socolofsky Environmental Fluid Mechanics Definition: Answers to how natural
processes in the hydrosphere change concentrations Transport processes: Diffusion (molecular and turbulent) Advection Transformation
processes: (key processes) Dissolution Chemical reactions Critter metabolisms Transport in the Hydrosphere
