Aquifer Constant given Drawdown in Well Solution

STEP 0: Pre-Calculation Summary

Formula Used

Aquifer Constant = (Discharge)/(2.72*(Drawdown in Well 1-Drawdown in Well 2))
T = (Q_w)/(2.72*(s₁-s₂))
This formula uses 4 Variables

Variables Used

Aquifer Constant - Aquifer Constant refers to the product of the hydraulic conductivity (K) and the thickness (b) of an aquifer and also known as coefficient of transmissibility.
Discharge - (Measured in Cubic Meter per Second) - Discharge refers to the volume of water that flows through the aquifer over a given period.
Drawdown in Well 1 - (Measured in Meter) - Drawdown in Well 1 refers to the reduction in water level caused by pumping in a well.
Drawdown in Well 2 - (Measured in Meter) - Drawdown in Well 2 refers to the reduction in water level caused by pumping in a well.

STEP 1: Convert Input(s) to Base Unit

Discharge: 0.911 Cubic Meter per Second --> 0.911 Cubic Meter per Second No Conversion Required
Drawdown in Well 1: 2.15 Meter --> 2.15 Meter No Conversion Required
Drawdown in Well 2: 2.136 Meter --> 2.136 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T = (Q_w)/(2.72*(s₁-s₂)) --> (0.911)/(2.72*(2.15-2.136))

Evaluating ... ...

T = 23.9233193277314

STEP 3: Convert Result to Output's Unit

23.9233193277314 --> No Conversion Required

FINAL ANSWER

23.9233193277314 ≈ 23.92332 <-- Aquifer Constant
