18. A well that pumps at a constant rate of 0.5m/s fully penetrates a confined aquifer of 34 m thickness. After a long period of pumping, near steady-state conditions, the measured drawdowns at two observations wells 50 and 100 m from the pumping well are 0.9 and 0.4m respectively. a) Calculate the hydraulic conductivity and transmissivity of the aquifer. b) Estimate the radius of influence of the pumping well c) Calculate the expected drawdown in the pumping well if the radius of well is 0.4m
