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.

STEP 1: Convert Input(s) to Base Unit

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
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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_w = (T*2.72*(s₁-s₂))/(log((r₂/r₁),10)) --> (24.67*2.72*(2.15-2.136))/(log((10/1.07),10))

Evaluating ... ...

Q_w = 0.91182949194757

STEP 3: Convert Result to Output's Unit

0.91182949194757 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.91182949194757 ≈ 0.911829 Cubic Meter per Second <-- Discharge
