D$\mathrm{.}3.$ A WWTP has three circular clarifiers $($diameter $100$ ft $)$ and

need a BOD reduction of at least $30\%.$ Base all values on

information provided in the FERH. Determine:

D$\mathrm{.}3.$a$.$ the overflow rate $gp\frac{d}{f}{t}^2$

D$\mathrm{.}3.$b$.$ the flow rate per tank $[$MGD$]$

D$\mathrm{.}3.$c$.$ the total flow rate in the plant $[$MGD$]$

D$\mathrm{.}3.$d$.$ the weir loading $gp\frac{d}{f}t$
