Problem Statement

• Consider the following experimental setup– L=1cm

– Darcy flux q=0.27cm/h

– Porosity n=0.3

– Cin is measured and given

– Cout is measured and given

• Assume that both adsorption and decay

processes occur and determine k, Kd, and

b using the data in the associated

spreadsheet (double click on the chart to

and change to sheet1 to get the data).
