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 in Well))^2
K_soil = (R_w/(3000*s_t))^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 in Well - (Measured in Meter) - The Total Drawdown in Well 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 in Well: 0.83 Meter --> 0.83 Meter No Conversion Required

STEP 2: Evaluate Formula
