A fully penetrating well of 30 cm diameter in an unconfined aquifer of saturated thickness 50 m was found to give the following draw down - discharge relationship under equillibium condition. If the radius of influence of the well can be assumed to be proportional to the discharge through the well, estimate the flow rate when draw down at the well is 6.0 m.
When draw-down at well is 3.0 m, then discharge is 600
When draw-down at well is 11.7 m, then discharge is 1800
