This formula uses 1 Functions, 7 Variables
Functions Used
log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)
Variables Used
Depth of Water in Well - (Measured in Meter) - Depth of Water in Well is measured above the impermeable layer.
Aquifer Thickness - (Measured in Meter) - Aquifer Thickness (at Midpoint between Equipotential lines) or otherwise is the thickness of aquifer in which the pore spaces of rock forming the aquifer may or may not be with water.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the flow rate of water that is extracted from or injected into a well.
Radius of Influence - (Measured in Meter) - Radius of Influence measured from the center of the well to the point where drawdown curve meets the original water table.
Radius of Well - (Measured in Meter) - Radius of Well is defined as the distance from center of well to its outer boundary.
Coefficient of Permeability - (Measured in Meter per Second) - Coefficient of Permeability is the velocity in meters or centimeters per second of water through soils.
Aquifer Thickness During Pumping - (Measured in Meter) - Aquifer Thickness During Pumping is the thickness of aquifer during pumping stage.
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: 1125 Centimeter per Second --> 11.25 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
hwell = bw-((Q*log((Rw/r),10))/(2.72*Kw*bp)) --> 14.15-((1.01*log((8.6/7.5),10))/(2.72*11.25*2.36))
Evaluating ... ...

STEP 3: Convert Result to Output's Unit
13.9146957936219 Meter --> No Conversion Required
FINAL ANSWER
13.9146957936219 13.9147 Meter <-- Depth of Water in Well
