An effluent stream consists of poly-dispersed aerosol, of uniform density (1.8 g/cm^3). the particle size distribution is lognormal, with sigma g=4.482, and geometric mass mean diameter equal to 10.0 micrometers. The effluent stream is cleaned with a device that has the following efficiency characteristics: Eta m(040 micrometers) =1. Calculate the overall aerosol mass removal efficiency for the device. If the aerosol concentration is 200 mg/m^3, and the device operates steadily with a flow rate equal to 1.5 m^3/s, calculate the particulate emission rate at the exit of the device.
