The depth of the impounded water in a $72 \mathrm{~m}$ long earthen dam is $6.2 \mathrm{~m}$, while the tail water is $2.2 \mathrm{~m}$ deep. The hydraulic conductivity of the isotropic and homogeneous soil-fill of the dam is $0.53 \mathrm{~m}$ day $^{-1}$. Flow net method is used to estimate seepage wherein the number of flow channels is 6 and the number of potential drops is 21 . The seepage rate through the dam in $\mathrm{m}^{3}$ day $^{-1}$ is____________
