The air stream in (a) flows at a rate of 4 m³/hr and is to be filtered by using particle collectors to achieve an emission limit of 10 mg/m³. Assuming that the collector's efficiency is 60 % which is independent of particle sizes, and each collector can only handle 2 m³/hr, determine (i) the minimum number of collector required to achieve the limit; (ii) the overall penetration factor of the system; and (iii) the particulate concentration at the exit of the dust collectors.
