A field test is conducted in a confined aquifer by pumping a constant discharge of 14. 9 m3/hrfrom a 20-cm-diamecer well. After an approximate steady state is reached, adrawdown of 0.98 mis measured in the pumped well. Also measured are draw downs of 0.78 m, 0.63 m, 0.59 m, and 0.56 m. respectively, at 3.0 m, 45.0 m, 90.0 m, and 150 m from the pumped well. Determine the trans missivity of th is aquife r. Also determine how far away from the well you must be before the drawdown becomes Jess than 0 .5 m.
