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?

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
