4. 10 points. Determine the hydraulic conductivity of an artesian aquifer being pumped by a well. The aquifer is composed of medium sand and is $$100\mathrm{ft}$$ thick. During a pumping test, the steadystate pumping rate is $$1200\mathrm{gpm}$$. The drawdown in an observation well $$75\mathrm{ft}$$ away is $$14\mathrm{ft}$$, and the drawdown in a second observation well $$500\mathrm{ft}$$ away is $$1.2\mathrm{ft}$$. Find $$K_t$$ in $$\mathrm{gpd}/{\mathrm{ft}}^2$$. Note: Use Thiem's method
