railway RRB JE (CBT I + CBT II) Mock Test 2024 Soil Mechanics and Foundation Engineering Well Hydraulics
A well with a radius of 0.3 m, including gravel envelope and developed zone, completely penetrates an unconfined aquifer with K = 25 m/day and an initial water table at 30m above the bottom of the aquifer. The well is pumped so that the water level in the well remains at 22 m above the bottom of the aquifer. Assuming that pumping has essentially no effect on water table height at 300 m from the well, determine the steady-state well discharge. (Neglect well losses).
