Drawdown given Well Loss Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Drawdown in Well = Aquifer loss+Head Loss in well
st = BQ+CQn
This formula uses 3 Variables
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.
Aquifer loss - (Measured in Meter) - Aquifer loss is product of discharge and aquifer loss coefficient.
Head Loss in well - (Measured in Meter) - The Head Loss in well is essentially the difference between the head of the aquifer immediately outside and in the well a head inside because of all these losses.
STEP 1: Convert Input(s) to Base Unit
Aquifer loss: 27.13 Meter --> 27.13 Meter No Conversion Required
Head Loss in well: 0.091 Meter --> 0.091 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
st = BQ+CQn --> 27.13+0.091
Evaluating ... ...
st = 27.221
STEP 3: Convert Result to Output's Unit
27.221 Meter --> No Conversion Required
FINAL ANSWER
27.221 Meter <-- Total Drawdown in Well
(Calculation completed in 00.004 seconds)

7 Aquifer Loss Calculators

Coefficient of Permeability given Aquifer Loss Coefficient
Go Coefficient of Permeability = (log((Radius of Influence/Radius of Well in Eviron. Engin.),e))/(2*pi*Aquifer Loss Coefficient*Aquifer Thickness)
Aquifer Loss Coefficient
Go Aquifer Loss Coefficient = (log((Radius of Influence/Radius of Well in Eviron. Engin.),e))/(2*pi*Coefficient of Permeability*Aquifer Thickness)
Radius of Well given Aquifer Loss Coefficient
Go Radius of Well in Eviron. Engin. = Radius of Influence in Eviron. Engin./exp(Aquifer Loss Coefficient*2*pi*Coefficient of Permeability*Aquifer Thickness)
Aquifer Loss given Drawdown
Go Aquifer loss = Total Drawdown in Well-Head Loss in well
Drawdown given Well Loss
Go Total Drawdown in Well = Aquifer loss+Head Loss in well
Aquifer Loss given Aquifer Loss Coefficient
Go Aquifer loss = Aquifer Loss Coefficient*Discharge
Discharge given Aquifer Loss
Go Discharge = Aquifer loss/Aquifer Loss Coefficient

Drawdown given Well Loss Formula

Total Drawdown in Well = Aquifer loss+Head Loss in well
st = BQ+CQn

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.

How to Calculate Drawdown given Well Loss?

Drawdown given Well Loss calculator uses Total Drawdown in Well = Aquifer loss+Head Loss in well to calculate the Total Drawdown in Well, The Drawdown given Well Loss is defined as the value of drawdown when we have prior information of other parameters used. Total Drawdown in Well is denoted by st symbol.

How to calculate Drawdown given Well Loss using this online calculator? To use this online calculator for Drawdown given Well Loss, enter Aquifer loss (BQ) & Head Loss in well (CQn) and hit the calculate button. Here is how the Drawdown given Well Loss calculation can be explained with given input values -> 27.221 = 27.13+0.091.
