Two wells, each with a $1-$m diameter, are located $100$ m apart in a confined aquifer with transmissivity $T=0\mathrm{.}04\frac{m^2}{m}in.$ The well to the west is pumped at a rate of $6\mathrm{.}6\frac{m^3}{h}r$ with steady state drawdown of $3$ m $.$ The well to the east is pumped at a rate of $10\mathrm{.}0\frac{m^3}{h}r$ with steady state drawdown of $4$ m $.$ Plot the individual and composite drawdowns as a function of distance along the line joining the wells.

A fully penetrating well pumps from a confined aquifer of thickness $20$ m with $K=1\frac{m}{d}.$ The radius of the well is $0\mathrm{.}25$ m and the pumping rate is $25\frac{m^3}{d}$ at steady state. Assume that the radius of influence $($or the distance at which drawdown is zero$)$ of the well is $1,250m.$ Compute the drawdown at the well if it is located $100$ m from an impermeable boundary.
