Using a design value of ${}_c=2$ day, and the kinetic constants given in Problem #$2,($Ks$=50$mg$/$L$,$ So$=200$mg$/$L$,$ Y$=\mathrm{.}6,$Kd$=\mathrm{.}06$d$-1)$ determine the effluent substrate concentration, the specific utilization rate $(-\frac{r_{su}}{x}),$ and food to microorganism ratio $),$ and the MLSS concentration in the reactor.
