STEP 1: Convert Input(s) to Base Unit

Aquifer Thickness: 14.15 Meter --> 14.15 Meter No Conversion Required
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second 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
Coefficient of Permeability in Well Hydraulics: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Aquifer Thickness During Pumping: 2.36 Meter --> 2.36 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_well = b_w-((Q*log((R_w/r),e))/(2*pi*K_WH*b_p)) --> 14.15-((1.01*log((8.6/7.5),e))/(2*pi*0.1*2.36))

Evaluating ... ...

h_well = 9.17313843994951

STEP 3: Convert Result to Output's Unit

9.17313843994951 Meter --> No Conversion Required

FINAL ANSWER

9.17313843994951 ≈ 9.173138 Meter <-- Depth of Water in Well
