EXAMPLE $7-10$ An artesian aquifer $10\mathrm{.}0$ m thick with a piezometric surface $40\mathrm{.}0$ m above the bottom confining layer is being pumped by a fully penetrating well. Steady state drawdowns of $5\mathrm{.}00$ m and $1\mathrm{.}00$ m were observed at two nonpumping wells located $20\mathrm{.}0$ m and $200\mathrm{.}0$ m $,$ respectively, from the pumped well. The pumped well is being pumped at a rate of $0\mathrm{.}016m^3*s^{-1}.$ Determine the hydraulic conductivity of the aquifer.
