Problem $3(6\mathrm{.}20)(40$pts$)$

A reverse$-$air baghouse is to be designed to remove fly ash from a power plant exhaust gas stream

flowing at $300,000$acfm. The airstream is at $300F$ and has a significant content of $SO2$ gas. Specify $($a$)$

the type of fabric, $($b$)$ the design filtering velocity, $f\frac{t}{m}in,($c$)$ number of compartments, $($d$)$ cloth area

per compartment, $f{t}^2.$

How would your answers change, if you needed to remove wood dust instead of fly ash and the flow

rate was $50,000$acfm?
