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)

The weight gain of women during pregnancy has an important effect on the birth weight of their children. If the weight gain is not adequate, the infant is more likely to be small and will tend to be less healthy. In a study conducted in two countries, weight gains (in kilogram) of women during the third trimester of pregnancy were measured. The results are summarized in the following table. Country n ȳ s2 Egypt 6 3.8 5.76 Kenya 10 3.3...
