A green coffee bean screening and handling operation emits 0.75 g/m3 of fine particulate matter. A reverse-air baghouse is being proposed for controlling the particulate emissions. The gas handling system has an exhaust flow rate of 3.3 m3 /s. A manufacturer has supplied the following data: Bag diameter 5 20 cm Bag length 5 12 m Air-to-cloth ratio 5 0.010 Bag cleaning 5 0.5 Estimate the number of bags required and the mass of particulate matter collected each day if the efficiency is 99 percent. Assume 24-hour operation
