$6\mathrm{.}5\mathrm{.}2$ A $0\mathrm{.}4-m$ diameter well is pumped continuously at a rate of $\frac{5\mathrm{.}61}{s}$ from an aquifer of transmissivity $108\frac{m^2}{?}$ day and storativity $2{10}^{-5}.$ How long will it take before the drawdown in the well reaches $2m?$

$6\mathrm{.}5\mathrm{.}3$ In problem $6\mathrm{.}5\mathrm{.}2,$ how long will it take before a drawdown at a distance of $400m$ from the well becomes $2m?$

$6\mathrm{.}5\mathrm{.}4$ In problem $6\mathrm{.}5\mathrm{.}2,$ determine the drawdown at a distance $200m$ from the well after $($a$)1hr,($b$)1$ day, and $($c$)1$ year of pumping.
