2. A 20-cm-diameter confined-aquifer well is pumped at a constant rate of 15 L/s. After 10 days of pumping, equilibrium hasn't been reached, and the drawdown measured at an observation well located 300 m from the main well is 285 mm. If it is assumed that the aquifer transmissibility is similar to that of an adjacent system, and equal to 600 m²/d, estimate: a) aquifer storage coefficient S. b) drawdown at the well, in m.

2. A 20-cm-diameter confined-aquifer well is pumped at a constant rate of 15 L/s. After 10 days of
pumping, equilibrium hasn't been reached, and the drawdown measured at an observation well
located 300 m from the main well is 285 mm. If it is assumed that the aquifer transmissibility is
similar to that of an adjacent system, and equal to 600 m²/d, estimate:
a) aquifer storage coefficient S.
b) drawdown at the well, in m.
