A 30cm diameter well penetrates vertically through an aquifer to an impermeable stratum located 18.0 m below the static water table. After a long period of pumping at a rate of 1.2 m3/min, the drawdown in test holes 11m and 35 m from the pumped well is found to be 3.05 and 1.62m respective. What is the hydraulic conductivity of the aquifer? Express in meters per day. What is its transmissivity? Express in cubic meters per day per meter. What is the drawdown in the pumped well?
