# Hydrogeology Fetters (average linear velocity)

9. A confined aquifer is 8 ft thick. The potentiometric surface drops 1.33 ft between two wells that are 685 ft apart. The hydraulic conductivity is 251 ft/day and the effective porosity is 0.27.

(A)How many cubic feet per day are moving through a strip of the aquifer that is 10 ft wide? Show all work.

(B)What is the average linear velocity? Show all work.
