Depth of Water in Well given Discharge in Confined Aquifer with Base 10 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depth of Water in Well = Aquifer Thickness-((Discharge*log((Radius of Influence/Radius of well),10))/(2.72*Coefficient of Permeability*Aquifer Thickness During Pumping))
h_well = b_w-((Q*log((R_w/r),10))/(2.72*K_w*b_p))
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 rate of flow of a liquid.
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: 15 Meter --> 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: 1000 Centimeter per Second --> 10 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),10))/(2.72*K_w*b_p)) --> 15-((1.01*log((8.6/7.5),10))/(2.72*10*2.36))

Evaluating ... ...

h_well = 14.7352827678247

STEP 3: Convert Result to Output's Unit

14.7352827678247 Meter --> No Conversion Required

FINAL ANSWER

14.7352827678247 ≈ 14.73528 Meter <-- Depth of Water in Well
