This formula uses 1 Functions, 6 Variables

Functions Used

log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)

Variables Used

Discharge - (Measured in Cubic Meter per Second) - Discharge is the flow rate of water that is extracted from or injected into a well.
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 - (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.
Length of Strainer - (Measured in Meter) - Length of Strainer is measured from bottom of aquifer to top of it.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Permeability in Well Hydraulics: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Total Drawdown: 0.83 Meter --> 0.83 Meter No Conversion Required
Length of Strainer: 2 Meter --> 2 Meter No Conversion Required
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Radius of Well in Well Hydraulics: 0.0037 Meter --> 0.0037 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (2.72*K_WH*s_t*(L+(s_t/2)))/(log((R_w/r^''),10)) --> (2.72*0.1*0.83*(2+(0.83/2)))/(log((8.6/0.0037),10))

Evaluating ... ...

Q = 1.83533998514263

STEP 3: Convert Result to Output's Unit

1.83533998514263 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.83533998514263 ≈ 1.83534 Cubic Meter per Second <-- Discharge
