1 Mass Balance Equations ± Lecture #8 ± open versus closed systems ± mass flow balance equation ± control volumes ± steady state mass balance problems (ICP#7) ± Reading: V: Ch 3 (pg. 45-50; pg. 56-58; Ex 3.5); Biosphere 2 Handout Overview ± What are the steps for setting up and solving mass balance equations? ± What is a control volume? ± What is a steady-state systems? ± What is a conservative substance? ± How do we solve conservative, steady-state mass balance problems (ICP#7)? Environmental Exposure Assessment ± chemical releases (mass concentrations) ± exposure pathway (media: air or water) ± chemical transport (mass transport models) ± system analysis (mass inputs and outputs around a control volume and mass balance modeling) ± concentration units ± flow and flux units Flow (pollutant point sources) ± flow and flux units are important for following the transport of pollutants from emission to receptors in water and air ± volumetric flow rate = Q( vol/time; L/d) ± mass flow rate of water = m = ρ H2O Q (mass/time) ( e.g., unit of g/d, where ρ H2O is density of water in units of g/L and Q is in units of L/d
