A groundwater pump has an unknown discharge extraction rate from a confined aquifer. The thickness is 8mand K=40m/day. To estimate its flow rate, 2 observation wells were installed. The first well is 2.5km from thepump and another well 6.9km from the first well further. The observed drawdown from original water level of150m were 12m in the 1st well and 7m in the 2nd well. If the groundwater pump has a diameter of 0.80m:Determine how far in meters from the pump its influence or no drawdown effect on water table. the answer is 60,033.1092= please provide the solution so that we can understand how they get that correct answer thank you
A permeability test was carried out from a well that sunk through a surfacelayer of loose sand. Figure below shows the arrangement of pumping wells, togetherwith relevant dimensions. Initially, the piezometric surface (ground water table) waslocated at a depth of 2.5m. When steady state was achieved at a pumping rate 38.5 m^3/hr, the following drawdowns were observed.
