STEP 1: Convert Input(s) to Base Unit
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
Radial Distance at Observation Well 2: 10 Meter --> 10 Meter No Conversion Required
Radial Distance at Observation Well 1: 1.07 Meter --> 1.07 Meter No Conversion Required
Modified Drawdown 1: 1.721 Meter --> 1.721 Meter No Conversion Required
Modified Drawdown 2: 1.714 Meter --> 1.714 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T = ((Q*log((r2/r1),e))/(2.72*(s1'-s2'))) --> ((1.01*log((10/1.07),e))/(2.72*(1.721-1.714)))
Evaluating ... ...
T = 23.7351070848246
STEP 3: Convert Result to Output's Unit
23.7351070848246 --> No Conversion Required
FINAL ANSWER
23.7351070848246 23.73511 <-- Aquifer Constant
