STEP 1: Convert Input(s) to Base Unit

Coefficient of Permeability in Well Hydraulics: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Depth of Water 2: 17.8644 Meter --> 17.8644 Meter No Conversion Required
Depth of Water 1: 17.85 Meter --> 17.85 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 = (pi*K_WH*(h₂^2-h₁^2))/(log((r₂/r₁),e)) --> (pi*0.1*(17.8644^2-17.85^2))/(log((10/1.07),e))
