Two groundwater wells are pumping near an observation well. When only pumping well 1 is operating, the steady-state drawdown at the observation well is 0.27 m when the pumping ate is 2.2 ML/d. When only pumping well 2 is operating, the steady-state drawdown at the observation well is 0.9 m when the Dumping rate is 0.7 ML/d. What is the steady-state drawdown at the observation well whe Dumping well 1 is pumping at 2.5 ML/d and, simultaneously, sumping well 2 is pumping at 2.3 ML/d?

Question
Two groundwater wells are pumping near an observation well.
When only pumping well 1 is operating, the steady-state
drawdown at the observation well is 0.27 m when the pumping
rate is 2.2 ML/d. When only pumping well 2 is operating, the
steady-state drawdown at the observation well is 0.9 m when the
pumping rate is 0.7 ML/d.
What is the steady-state drawdown at the observation well when
pumping well 1 is pumping at 2.5 ML/d and, simultaneously,
pumping well 2 is pumping at 2.3 ML/d?
