Extracted text: . A 20 mm diameter well fully penetrates a confined aquifer of 30 m depth. For a pumpage of 35 litres/second the steady drawdowns at 100 m and 300 m distances from the well are observed as 3.2 m and 2.5 m respectively. Estimate the coefficient of permeability in m/day and transmissibility of the aquifer in m2 per day. Estimate also the drawdown at the well.
