A 400 mm diameter well fully penetrates a confined aquifer of thickness 20 m is pumped at a constant rate of 2500 m/day. The drawdown in the pumping well is observed as 4 m and the radius of influence is at a distance of 100 m. (i) Calculate the transmissivity of the aquifer; (ii) Determine the hydraulic conductivity of the aquifer material and draw the neat sketch of the well
