Three streams of polluted air are combined prior to treatment in an electrostatic precipitator (ESP). The flow and particulate concentration of each stream are 600 cfm at150 mg/m^3, 700 cfm at 200 mg/m^3, and 500 cfm at 1000 mg/m^3. If the electrostatic precipitator has an 85% removal efficiency, what are the air flow and particulate concentration of the discharge?
