Round off answer to two decimal places unless otherwise stated in the problem
Developer ABC is preparing for an upcoming project and recognizes the utmost importance of understanding the site's soil conditions. To assess soil permeability, a pumping test was conducted within a 25-meter-thick soil bed. This test provided invaluable insights into the site's hydrogeological features. Gravelly layers were found within the first 2 m, and the initial groundwater level was located at a depth of 3.5 m from the ground level. Throughout the test, a pumping rate of 3.73 m³ in every five minutes was consistently maintained. Significant observations were made from wells positioned at distances of 18 m and 27 m from the edge of a 40-meter-diameter pumping well, indicating drawdowns of 2.1 m and 1.8 m, respectively. a. b. C. Determine the hydraulic conductivity, in cm/s. Determine the radius of influence (in m) and round your answer to the nearest whole number. Determine the maximum possible drawdown, in m (assumed it will occur at the well face; any of the observation can be used as reference).
