QI. s) Q1: A 1 m diameter well penetrates vertically through a confined aquifer (30 m) thick. When the well is pumped at (2712 m³/day), the drawdown in a well 15 m away from pumped well is 1.8 m; while the drawdown in another well 50 m away from pumped well is 0.5 m. Take the maximum head is 40 m. 1- Determine the transmissivity. 2- What is the approximate head in the first well? 3- What is the approximate head in the second well? 4- What is the approximate head in the pumped well for steady-state conditions? 5- What is the approximate drawdown in the pumped well?
