(400 gpm). 9.16. Determine the maximum steady-state pumping rate in lps (gpm) for a 305-mm (12-in) diameter well installed in an unconfined aquifer if the allowable drawdown at the well is limited to 8.0 m (26.2 ft). The aquifer has a saturated thickness of 12.0 m (39,4 and a hydraulic conductivity of 40 m/day (131.2 ft/day). The radius of influence for the well is 2,000 m (6,560 ft). 9.17. Determine the maximum steady-state pumping rate for the well in Problem 9.16 if the allowable drawdown at the well is limited to 6.0 m (19.7 ft). 9.18. Determine the drawdown at the well and 30 m (98.4 ft) from the well in Problem 9.16 du otota discharge of 18.9 lps (300 gpm).
