The catalyst regeneration unit in an oil refinery is generating a flue gas containing air and dust particles. The flue gas flow rate is
6(m^(3))/(s)
at
200\deg C
and 1 atm . The density of flue gas is
1.2k(g)/(m^(3))
and the density of dust particles is
2000k(g)/(m^(3))
. The viscosity of flue gas is
1.8\times 10^(-5)k(g)/(m).s
. Design a settling chamber that can be used to remove
80%
of
60\mu m
particles for regulatory compliance. The recommended gas velocity passing through the effective chamber is
3(m)/(s)
. The available floor space is 2 m wide and 5 m long. ***Calculation of Re to identify type of gas flow in the chamber is required. Show your analysis and provide the following design information. (15 marks)

A sketch with dimensions of the effective chamber (width, length and height)
?
If you choose to insert horizontal plates in the chamber, you must identify mumber of horizontal plates and plate spacing.
