Question $2$

A green coffee bean screening and handling operation emits $0\mathrm{.}75\frac{g}{m^3}$ of fine particulate

matter. A reverse$-$air baghouse with active area of $330m^2$ is being proposed for

controlling the particulate emissions. The gas handling system has an exhaust flow rate of

$3\mathrm{.}3\frac{m^3}{s}.$ A manufacturer has supplied the following data:

Bag diameter $=20cm$

Bag length $=12m$

Estimate

the number of bags required and

the mass of particulate matter collected each day if the efficiency is $99$ percent.

Assume $24-$hour operation
