Variables Used
Radius of well - (Measured in Meter) - Radius of well 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 Permeability in Well Hydraulics - (Measured in Meter per Second) - Coefficient of Permeability in Well Hydraulics of soil in well hydraulics describes how easily a liquid will move through the soil.
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.
Length of strainer - (Measured in Meter) - Length of strainer is measured from bottom of aquifer to top of it.
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
Coefficient of Permeability in Well Hydraulics: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Total Drawdown in Well: 0.83 Meter --> 0.83 Meter No Conversion Required
Length of strainer: 2 Meter --> 2 Meter No Conversion Required
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
r = Rw/(10^((2.72*KWH*st*(L+(st/2)))/Q)) --> 8.6/(10^((2.72*0.1*0.83*(2+(0.83/2)))/1.01))

What is discharge ?

The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate.
