An earthen dam measures $200m$ from the upstream face to the downstream face and is underlain by an impermeable bedrock. The average hydraulic conductivity of the material of which the dam is constructed is $0\mathrm{.}065\frac{m}{?}$ day. If the water surface elevations in the reservoir and the tailwater are $25m$ and $4\mathrm{.}5m,$ respectively, calculate the flow rate of leakage $($in $\frac{m^3}{?}$ day$)$ from the reservoir to the tailwater assuming the dam is $100m$ wide
