Variables Used

Aquifer Constant - Aquifer Constant is also known as coefficient of transmissibility.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid through well or aquifers.
Radial Distance at Observation Well 2 - (Measured in Meter) - Radial Distance at Observation Well 2 is the value of radial distance from well 2 when we have prior information of other parameters used.
Radial Distance at Observation Well 1 - (Measured in Meter) - Radial Distance at Observation Well 1 is the value of radial distance from well 1 when we have prior information of other parameters used.
Modified Drawdown 1 - (Measured in Meter) - Modified Drawdown 1 is the modified value of drawdown for well 1.
Modified Drawdown 2 - (Measured in Meter) - Modified Drawdown 2 is the modified value of drawdown for well 2.

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
