Example $6-$ Thiem's Equation for the Drawdown due to Wells

The diameter of a well extending into an unconfined aquifer is $45$ cm $.$ The thickness of aquifer is $30$ m $,$ and the hydraulic conductivity is $0\mathrm{.}034\frac{m}{m}in.$ There are two observing wells whose distances to the well's center are $32$ m and $75$ m $.$ The corresponding drawdowns in these two wells are $7$ m and $6\mathrm{.}5$ m $,$ respectively. Find the pumping discharge $($ cms $)$ in the well.
