Groundwater Wells and Pumps

In a pumping test on a confined aquifer, steady well discharge is $Q = 1200\text{ m}^3/\text{day}$. Drawdowns at observation wells at $r_1 = 10\text{ m}$ and $r_2 = 100\text{ m}$ (so $\ln(r_2/r_1) = \ln(10) \approx 2.3026$) are $s_1 = 2.0\text{ m}$ and $s_2 = 0.5\text{ m}$ (difference $s_1 - s_2 = 1.5\text{ m}$). transmissivity $T$ in $\text{m}^2/\text{day}$ is (rounded off to one decimal place):
