The dust discharged from the milling process is controlled by the filter dust collection facility.

Rice is transferred to a mill at $16\frac{m}{s}$ through ducts $,0\mathrm{.}7850\mathrm{.}4mm)$ and then milled $($Exit $1).$ The milled rice is transferred to a stone mill at $20\frac{m}{s}$ through ducts $(450,0\mathrm{.}7850\mathrm{.}45mm),$ precipitated stone, and unloaded through $10$ ducts $(100,0\mathrm{.}7850\mathrm{.}1mm)$ which are transfer facilities $($Exit $2).$

The raw material usage is $35$ tons$/$day of rice, the operation time is $8$ hours$/$day$,$ and the emission coefficient is $0\mathrm{.}32k\frac{g}{?}$ ton.

Q$1)$ Find the amount of exhaust gas $($Sm$3/$min$)$ and the concentration of dust $($mg$/$Sm$3)$ from outlets $1$ and $2$

Q$2)$ Find the filter area, the number of filter cloths, and the actual filter speed of the filter collection facility and design the arrangement of the bag filter
