A well was constructed to pump water from a confined aquifer. Two observation wells were constructed at distances of 350 m and 800m respectively. At a steady pumping rate of 0.39 m^3/min, the drawdown in the observation wells were respectively equal to 1.6 m and 7.8 m. Diameter of the test well is 0.95 m and thickness of confined aquifer is 16 m. a. Determine the hydraulic conductivity of the soil in m/min. (IN EXPONENTIAL FORM AND IN 2 DECIMAL PLACES) b. Determine the drawdown at the test well in m. (IN 2 DECIMAL PLACES) c. What is the value of the transmissivity of the confined aquifer in m^2/day? (IN 2 DECIMAL PLACES)

Consider two horizonal soil layers, each is isotropic, the upper layer 1 is sitting directly on the top of bottom layer 2. Layer 1 has a thickness of 2 m and a hydraulic conductivity of 0.26 m/day and layer 2 has a thickness of 4 m and a hydraulic conductivity of 0.95 m/day. In this case, calculate the equivalent horizontal hydraulic conductivity in m/day.
