Length of Strainer given Discharge Solution

STEP 0: Pre-Calculation Summary
Formula Used
Length of strainer = ((Discharge*log((Radius of Influence/Radius of well),10))/(2.72*Coefficient of Permeability in Well Hydraulics*Total Drawdown in Well))-(Total Drawdown in Well/2)
L = ((Q*log((Rw/r),10))/(2.72*KWH*st))-(st/2)
This formula uses 1 Functions, 6 Variables
Functions Used
log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)
Variables Used
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.
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 - (Measured in Meter) - Radius of well is defined as the distance from center of well to its outer boundary.
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.
STEP 1: Convert Input(s) to Base Unit
Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
Radius of Influence: 8.6 Meter --> 8.6 Meter No Conversion Required
Radius of well: 7.5 Meter --> 7.5 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
STEP 2: Evaluate Formula
Substituting Input Values in Formula
L = ((Q*log((Rw/r),10))/(2.72*KWH*st))-(st/2) --> ((1.01*log((8.6/7.5),10))/(2.72*0.1*0.83))-(0.83/2)
Evaluating ... ...
L = 74.8539961365957
STEP 3: Convert Result to Output's Unit
74.8539961365957 Meter --> No Conversion Required
FINAL ANSWER
74.8539961365957 74.854 Meter <-- Length of strainer

5 Aquifer Thickness Calculators

Thickness of Aquifer given Discharge in Unconfined Aquifer
Go Thickness of Unconfined Aquifer = sqrt(Depth of Water^2+(Discharge*log((Radius of Influence/Radius of well),e))/(pi*Coefficient of Permeability in Well Hydraulics))
Length of Strainer given Discharge
Go Length of strainer = ((Discharge*log((Radius of Influence/Radius of well),10))/(2.72*Coefficient of Permeability in Well Hydraulics*Total Drawdown in Well))-(Total Drawdown in Well/2)
Thickness of Aquifer for Discharge in Unconfined Aquifer with Base 10
Go Thickness of Unconfined Aquifer = sqrt(Depth of Water^2+(Discharge*log((Radius of Influence/Radius of well),10))/(1.36*Standard Coefficient of Permeability at 20°C))
Thickness of Aquifer given Drawdown Value measured at Well
Go Thickness of Unconfined Aquifer = Total Drawdown in Well+Depth of Water
Cross-section Area of Soil Mass given Flow Velocity
Go Area of Cross Section in Enviro. Engin. = (Rate of Flow/Flow Velocity)

Length of Strainer given Discharge Formula

What is drawdown ?

A drawdown is a peak-to-trough decline during a specific period for an investment, trading account, or fund. A drawdown is usually quoted as the percentage between the peak and the subsequent trough.
