An air pollution control technology device is receiving a waste gas stream 40m3/minute that contains 2000g/m3 of Particulate Matter (PM) or aerosols. The emission from the control device has PM concentration of 80Pg/m3. Use the steps shown below to calculate the removal efficiency, expressed as a %, of PM (Particulate Matter), as removed the waste gas stream (a) What mass of PM is coming into the pollution control device in g/ minutes ?(1.5pts) (b) What mass of PM is escaping out of the air pollution control device in g/minutes derth pusat? (1.5pts) (c) How much PM is removed from the waste gas air stream in g/ minutes (d) What is the efficiency of the pollution control technology__ (irm? (1.5 pts)
