Question: 3 . 2 6 well is being pumped at a constant rate of 0 . 0 0 4 m 3 s . Given that T

3.26 well is being pumped at a constant rate of 0.004m3s. Given that T=0.0028m2s,r=100m, and the storage coefficient =0.001, find the drawdown in the observation well for a time period of (a)1 hr and (b)24 hr .
3.27 A well is being pumped at a constant rate of 0.003m3s. Given that T=0.0028m2s, the storage coefficient =0.001, and the time since pumping began is 12 hr , find the drawdown in an observation well for a radial distance of (a)150 m and (b)500 m .
3.28 A 12-in well fully penetrates a confined aquifer 100 ft thick. The coefficient of permeabiity is 600gpdft2. The difference in drawdown between two test wells 45 and 120 ft away is 8 ft . Find the rate of flow delivered by the well.
3.29. Determine the permeability of an artesian aquifer being pumped by a fully penetrating well. The aquifer is composed of medium sand and is 100 ft thick. The steady-state pumping rate is 1200 gpm . The drawdown in an observation well 75 ft away is 14 ft , and the drawdown in a second observation well 500 ft away is 1.2 ft . Find Kf in gpdft2.
3.30 Consider a confined aquifer with a coefficient of transmissibility T=680ft3dayft. At t=5min, the drawdown s=5.6ft; at 50min,s=23.1ft; and at 100min,s=28.2ft. The observation well is 75 ft away from the pumping well. Find the discharge of the well.
3.31 Assume that an aquifer is being pumped at a rate of 300 gpm . The aquifer is confined and the pumping test data are given below. Find the coefficient of transmissibility T and the storage coefficient S for r=60ft.
