Variables Used
Radius of Well in Well Hydraulics - (Measured in Meter) - Radius of Well in Well Hydraulics is defined as the distance from center of well to its outer boundary.
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.
Coefficient of Transmissibility - (Measured in Square Meter per Second) - Coefficient of transmissibility is defined as the rate of flow of water in gallons per day through a vertical strip of the aquifer.
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.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid.
STEP 1: Convert Input(s) to Base Unit
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
