Thickness of Aquifer for Discharge in Unconfined Aquifer with Base 10 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thickness of Aquifer = sqrt(Depth of Water^2+(Discharge*log((Radius of Influence/Radius of Well),10))/(1.36*Standard Coefficient of Permeability at 20°C))
b = sqrt(h_w^2+(Q*log((R_w/r),10))/(1.36*K_s))
This formula uses 2 Functions, 6 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)

Variables Used

Thickness of Aquifer - (Measured in Meter) - The Thickness of Aquifer vertical thickness of the hydro geologically defined aquifer in which the pore spaces of the rock forming the aquifer are filled with water.
Depth of Water - (Measured in Meter) - Depth of Water is the depth in the well measured above the impermeable layer.
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.
Standard Coefficient of Permeability at 20°C - Standard Coefficient of Permeability at 20°C of pure water at standard temperature.

STEP 1: Convert Input(s) to Base Unit

Depth of Water: 2.44 Meter --> 2.44 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
Standard Coefficient of Permeability at 20°C: 8.34 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

b = sqrt(h_w^2+(Q*log((R_w/r),10))/(1.36*K_s)) --> sqrt(2.44^2+(1.01*log((8.6/7.5),10))/(1.36*8.34))

Evaluating ... ...

b = 2.72979117793667

STEP 3: Convert Result to Output's Unit

2.72979117793667 Meter --> No Conversion Required

FINAL ANSWER

2.72979117793667 ≈ 2.729791 Meter <-- Thickness of Aquifer
