2. An aquifer test is performed on a well in an aquifer of practical infinite aerial extent (nohydrogeologic boundaries in the nearby vicinity). The aquifer is confined with no vertical leakage.The pumped well is pumped at a constant rate of 400 gpm. The draw down is measured in an observation well located 35 feet from the pumping well. The data from the aquifer test are given in the table below. Analyze the data below and determine T (30 Pts).
