A cyclone manufacturer provided you with the following partition curve for your desired feed rate.

a$)$ What is the $d_{se}$ and bypass ratio for this cyclone?

$(2)$

The feed to our cyclone will have the following cumulative partiele size distribution.

$\backslash$table$[[,$Feed$],[$Sieve size,Cumulative Passing$],[$microns$,$$$6],[212,100],[150,95],[105,70],[74,20],[53,15]]$

b$)$ Calculate the expected cumulative size distributions for both the overflow and the underflow. Show all working.

c$)$ What is the mass recovery to the underflow?

d$)$ As the cyclone wears, what would you expect to happen to the cut$-$size and the mass recovery to the underflow and why?
