Problem $2.$

Using a surface overflow rate of $26\mathrm{.}00\frac{m}{d}$ and a detention time of $2\mathrm{.}00$ hours, size of a sedimentation tank for the average flow rate of $0\mathrm{.}4m\frac{3}{s}$ would be: $($assume a Length to Width Ratio of $10)$

a$.$ Volume cubic meter

b$.$ Depth $-$meter

c$.$ Width$--$meter

d$.$ Length
