![1. The following data are obtained from a cavity tube well: Discharge 0.062 m3
Drawdown 5.3 m Permeability of the aquifer 62 m/day Depth of cavity 23 cm
Radius of influence 183 m Determine the radius and width of cavity
2. A 26-cm well penetrates 38 m below static water level (GWT). After a long
period of pumping at a rate of 2200 Ipm, the drawdowns in the observation wells
at 16 m and 38 m from the pumped well are 1.5 m and 0.8 m, respectively.
Determine the following: a. the transmissibility of the aquifer b. the drawdown in
the pumped well assuming R = 350 m c. the specific capacity of the well
3. An artesian aquifer, 45 m thick has a porosity of 43% and bulk modulus of
compression 2500 kg/cm2. Estimate the storage coefficient of the aquifer. What
fraction of this is attributable to the expansibility of water? Bulk modulus of
elasticity of water = 2.4 x 104 kg/cm2.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5ce2b1b6-8850-46e9-89a8-e964a007e4e3%2Fc84cb909-c560-4a46-b1cb-db34f99247e3%2Fzopiyof_processed.png&w=3840&q=75)
