Drawdown at Well given Radius of Influence Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Drawdown in Well = Radius of Influence/(3000*sqrt(Coefficient of Permeability in Well Hydraulics))
st = Rw/(3000*sqrt(KWH))
This formula uses 1 Functions, 3 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)
Variables Used
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.
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 Permeability in Well Hydraulics - (Measured in Centimeter per Second) - Coefficient of Permeability in Well Hydraulics of soil in well hydraulics describes how easily a liquid will move through the soil.
STEP 1: Convert Input(s) to Base Unit
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Coefficient of Permeability in Well Hydraulics: 10 Centimeter per Second --> 10 Centimeter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
st = Rw/(3000*sqrt(KWH)) --> 8.6/(3000*sqrt(10))
Evaluating ... ...
st = 0.000906519595914935
STEP 3: Convert Result to Output's Unit
0.000906519595914935 Meter --> No Conversion Required
FINAL ANSWER
0.000906519595914935 0.000907 Meter <-- Total Drawdown in Well
(Calculation completed in 00.004 seconds)
