A 1-m-diameter well fully penetrates a confined aquifer which is 20 m thick. After a constant pumping of 105 m/hr, the drawdown observed in a monitoring well located 15 m away is 1.8 m and the drawdown in another monitoring well 50 m away is 0.5 m. The initial piezometric level is 30 m above the datum. Determine the transmissivity of the aquifer and the approximate drawdown in the well. Estimate the radius of influence of the pumping well.
