r₁ = r₂/10^((2.72*T*(s₁-s₂))/Q_w)
This formula uses 6 Variables

Variables Used

Radial Distance at Observation Well 1 - (Measured in Meter) - Radial distance at Observation Well 1 refers to the horizontal distance from the center of a pumping well to the observation well, where groundwater levels are monitored.
Radial Distance at Observation Well 2 - (Measured in Meter) - Radial distance at Observation Well 2 refers to the horizontal distance from the center of a pumping well to the observation well, where groundwater levels are monitored.
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.
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.
Discharge - (Measured in Cubic Meter per Second) - Discharge refers to the volume of water that flows through the aquifer over a given period.

STEP 1: Convert Input(s) to Base Unit

Radial Distance at Observation Well 2: 10 Meter --> 10 Meter No Conversion Required
Aquifer Constant: 24.67 --> 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
Discharge: 0.911 Cubic Meter per Second --> 0.911 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r₁ = r₂/10^((2.72*T*(s₁-s₂))/Q_w) --> 10/10^((2.72*24.67*(2.15-2.136))/0.911)

Evaluating ... ...

r₁ = 0.930654719304923

STEP 3: Convert Result to Output's Unit

0.930654719304923 Meter --> No Conversion Required

FINAL ANSWER

0.930654719304923 ≈ 0.930655 Meter <-- Radial Distance at Observation Well 1
