QUESTION 8 

A pump test was conducted with a well drilled into a 12' thick confined aquifer. The pump produced a steady flow rate of 205 gallons per minute and the two observation wells that are located 75 feet and 150 feet from the center of the well had water levels that were 16 feet and 20 feet above the bottom of the confined aquifer. Calculate the coefficient of permeability of the aquifer's soil.

1.05 feet per second 

QUESTION 9 

A 10 foot by 12 foot rectangular area at-grade footing supports a uniform load of 5,000 pounds per square foot. Find the vertical stress increment due to this loading condition 12 feet below the ground surface using the approximate method. 

11,289 pounds per square foot 

8,378 pounds per square foot 

425 pounds per square foot 

1,136 pounds per square foot
