A soil core (cylindrical) is extracted during a well installation. It has a dry weight of 2 kg, a length of 50 cm, and a diameter of 5.2 cm.
a. Estimate the bulk density and the porosity of the core (assume it is quartz sandstone (density = 2.65 g/cm3 ).
b. How much water is needed to achieve an average water saturation of 30%?
c. Estimate the specific yield if the specific retention is 0.06.
d. How much water would yielded from this sandstone aquifer if the water table drops 5 feet? (Assume the aquifer is 1 square kilometer). Report in cubic feet and gallons)
