Question $1(6$ points$)$

Listen

A baghouse from a mass$-$burn incinerator unit holds a total of $50$ bags for particulate removal. A single bag is cylindrical in shape and measures $22$ cm diameter and $4\mathrm{.}5$ m length. If the baghouse unit $(52$ bags$)$ is to treat $16,500\frac{m^3}{h}$ of flue gas, calculate the effective filtration velocity in meters per minute if the inlet loading is $150g\frac{r}{m^3}$ and the unit operates at $90\%$ collection efficiency. Note that $1$ kg of collected residue is $15,430$ grains $).$
