Variables Used

Aquifer Loss Coefficient - Aquifer Loss Coefficient is constant for a given flow rate.
Radius of Investigation - (Measured in Meter) - The Radius of Investigation refers to the maximum distance from a pumping well where the properties of the aquifer significantly influence the drawdown at the well.
Radius of Well - (Measured in Meter) - The Radius of Well refers to the distance from center of well to its outer boundary.
Coefficient of Permeability - (Measured in Meter per Second) - The Coefficient of Permeability refers to the measure how easily a fluid can flow through a porous material, such as soil or rock, also known as hydraulic conductivity.
Aquifer Thickness - (Measured in Meter) - The Aquifer Thickness (at Midpoint between Equipotential lines) refers to the thickness of aquifer in which the pore spaces of rock forming the aquifer may or may not be with water.

STEP 1: Convert Input(s) to Base Unit

Radius of Investigation: 100 Meter --> 100 Meter No Conversion Required
Radius of Well: 2.94 Meter --> 2.94 Meter No Conversion Required
Coefficient of Permeability: 0.01 Centimeter per Second --> 0.0001 Meter per Second (Check conversion here)
Aquifer Thickness: 15 Meter --> 15 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

B = (log((R/r^'),e))/(2*pi*k*b_w) --> (log((100/2.94),e))/(2*pi*0.0001*15)

What is Aquifer?

An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.

How to Calculate Aquifer Loss Coefficient?

Aquifer Loss Coefficient calculator uses Aquifer Loss Coefficient = (log((Radius of Investigation/Radius of Well),e))/(2*pi*Coefficient of Permeability*Aquifer Thickness) to calculate the Aquifer Loss Coefficient, The Aquifer Loss Coefficient formula is defined as the measure of the loss of energy or head that occurs as water flows through an aquifer, which is a critical component in the design and operation of groundwater wells and aquifer systems. Aquifer Loss Coefficient is denoted by B symbol.

How to calculate Aquifer Loss Coefficient using this online calculator? To use this online calculator for Aquifer Loss Coefficient, enter Radius of Investigation (R), Radius of Well (r^'), Coefficient of Permeability (k) & Aquifer Thickness (b_w) and hit the calculate button. Here is how the Aquifer Loss Coefficient calculation can be explained with given input values -> 30.0852 = (log((100/2.94),e))/(2*pi*0.0001*15).
