A gravity settling chamber is used to collect particles 50m in diameter and 1400kg/m3 density from a stream of air at 1atm and 300K with a volumetric rate of 2.5m3/s. The overall chamber is 2m high, 4m wide and will have 25 trays including the bottom surface. (a) How long is the chamber for 100% removal efficiency? (b) Is the flow laminar? (\&) What is the collection efficiency for a 10m particle using the length calculated in part (a)?
