A multi-tray settling chamber is to be designed to handle 20 m/s of air at 293 K. The minimum particle size that can be collected at 100% efficiency is estimated to be 58 um of density 2000 kg/m If the chamber is 2 m wide (W), 4 m long (L), and the trays are to be spaced 0.5 m apart (AH), assuming laminar flow inside the chamber and density of the gas (Pg) =0, how many 2021ht02548-8247 m2548-82470 70-20 trays will be required? (Data: g at 293 K = 1.81 x 10-5 kg/m.s, kinematic viscosity of air (g/Pg) = 1.51 x 10-5 m/s, also H= nAH). Part II: Is the laminar flow assumption justified? Show it using proper calculations. If not, then with the above calculated number of trays, what will be the collection efficiency of the chamber if 45 m particles are to be removed?
