4-48. If a fully penetrating well in a 99.99 m thick artesian aquifer pumping at a rate of 0.0020 m³/s for 1,812 days causes a drawdown of 12.73 m at an observation well 280.00 m from the pumping well, how much drawdown will occur at an observation well 1,492.0 m away? The original piezometric surface was 170.89 m above the bottom confining layer. The aquifer material is sandstone. Report your answer to two decimal places.
