Variables Used

Coefficient of Transmissibility - (Measured in Square Meter per Second) - Coefficient of Transmissibility is defined as the rate of flow of water in gallons per day through a vertical strip of the aquifer.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the flow rate of water that is extracted from or injected into a well.
Total Drawdown - (Measured in Meter) - The Total Drawdown is defined as the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
Radius of Influence - (Measured in Meter) - Radius of Influence measured from the center of the well to the point where drawdown curve meets the original water table.
Radius of Well - (Measured in Meter) - Radius of Well is defined as the distance from center of well to its outer boundary.

STEP 1: Convert Input(s) to Base Unit

Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
Total Drawdown: 0.83 Meter --> 0.83 Meter No Conversion Required
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Radius of Well: 7.5 Meter --> 7.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_envi = Q/((2*pi*s_t)/(log((R_w/r),e))) --> 1.01/((2*pi*0.83)/(log((8.6/7.5),e)))

Evaluating ... ...

T_envi = 1.41510762430351

STEP 3: Convert Result to Output's Unit

1.41510762430351 Square Meter per Second --> No Conversion Required

FINAL ANSWER

1.41510762430351 ≈ 1.415108 Square Meter per Second <-- Coefficient of Transmissibility
