Coefficient of Permeability given Radius of Influence Solution

STEP 0: Pre-Calculation Summary
Formula Used
Coefficient of Permeability of Soil Particle = (Radius of Influence/(3000*Total Drawdown))^2
Ksoil = (Rw/(3000*st))^2
This formula uses 3 Variables
Variables Used
Coefficient of Permeability of Soil Particle - (Measured in Meter per Second) - Coefficient of Permeability of Soil Particle describes how easily a liquid will move through the soil.
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.
Total Drawdown - (Measured in Meter) - The Total Drawdown is defined as the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
STEP 1: Convert Input(s) to Base Unit
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Total Drawdown: 0.83 Meter --> 0.83 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ksoil = (Rw/(3000*st))^2 --> (8.6/(3000*0.83))^2
Evaluating ... ...
Ksoil = 1.19288398574217E-05
STEP 3: Convert Result to Output's Unit
1.19288398574217E-05 Meter per Second -->0.00119288398574217 Centimeter per Second (Check conversion ​here)
