$(20)$ A well is located in an aquifer with a conductivity of $20\mathrm{.}5\frac{m}{d}$ and a storativity of $0\mathrm{.}0052.$ The aquifer is $35\mathrm{.}5m$ thick and is pumped at a rate of $2500\frac{m^3}{d}.$ What is the drawdown at a distance of $12\mathrm{.}0m$ from the well after $2$ days of pumping? See attached Well Function Table below.
