A well penetrates an unconfined aquifer. Prior to pumping, the water level (head) is 25 meters. After a long period of pumping at a constate rate of 0.05 cubic meters per second, the drawdowns at distances of 50 and 150 meters from the well were observed to be three and 1.2 meters respectively. Computer the hydraulic conductivity of the aquifer and the radius of influence of the pumping well.
