2) The coefficient of storage of a confined aquifer is found to be 6.8x10-4 as a result of a pumping test. The thickness of the aquifer is about 50 m and the porosity of the aquifer is 25%. Determine the fractions of the expansibility of water and compressibility of the aquifer skeleton in making up the storage coefficient of the aquifer. Hint: See example 2.52 of the Text Book or the class notes.
