A $30 \mathrm{~cm}$ diameter well fully penetrates an unconfined aquifer of saturated thickness $20 \mathrm{~m}$ with hydraulic conductivity of $10 \mathrm{~m} /$ day. Under the steady pumping rate for a long time, the drawdowns in two observation wells located at $10 \mathrm{~m}$ and $100 \mathrm{~m}$ from the pumping well are $5 \mathrm{~m}$ and $1 \mathrm{~m}$, respectively. The corresponding pumping rate (in $\mathrm{m}^{3} /$ day) from the well is $\_\_\_\_\_\_\_\_$. (rounded off to $2$ decimal places).
