Discharge given Difference between Modified Drawdowns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge = (2.72*Difference in Drawdowns*Aquifer Constant)
Q = (2.72*Δs*T)
This formula uses 3 Variables

Variables Used

Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid.
Difference in Drawdowns - (Measured in Meter) - Difference in Drawdowns at the two wells.
Aquifer Constant - Aquifer Constant is also known as coefficient of transmissibility.

STEP 1: Convert Input(s) to Base Unit

Difference in Drawdowns: 0.014 Meter --> 0.014 Meter No Conversion Required
Aquifer Constant: 24.67 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (2.72*Δs*T) --> (2.72*0.014*24.67)

Evaluating ... ...

Q = 0.9394336

STEP 3: Convert Result to Output's Unit

0.9394336 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.9394336 ≈ 0.939434 Cubic Meter per Second <-- Discharge

(Calculation completed in 00.004 seconds)

< 8 Modified Discharge And Drawdown in Unconfined Aquifers Calculators

Unconfined Aquifer Discharge given Aquifer Constant

Go Discharge = Aquifer Constant/((log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),e))/(2.72*(Modified Drawdown 1-Modified Drawdown 2)))

Modified Drawdown in Well 1 given Aquifer Constant

Go Modified Drawdown 1 = Modified Drawdown 2+((Discharge*log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),e))/(2.72*Aquifer Constant))

Modified Drawdown in Well 2 given Aquifer Constant

Go Modified Drawdown 2 = Modified Drawdown 1-((Discharge*log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),e))/(2.72*Aquifer Constant))

Thickness of Aquifer from Impermeable Layer given Modified Drawdown in Well 1

Go Unconfined Aquifer Thickness = ((Drawdown in well 1)^2/(2*(Drawdown in well 1-Modified Drawdown 1)))

Thickness of Aquifer from Impermeable Layer given Modified Drawdown in Well 2

Go Unconfined Aquifer Thickness = ((Drawdown in well 2)^2/(2*(Drawdown in well 2-Modified Drawdown 2)))

Modified Drawdown in Well 1

Go Modified Drawdown 1 = Drawdown in well 1-((Drawdown in well 1)^2/(2*Initial Aquifer Thickness))

Modified Drawdown in Well 2

Go Modified Drawdown 2 = Drawdown in well 2-((Drawdown in well 2)^2/(2*Initial Aquifer Thickness))

Discharge given Difference between Modified Drawdowns

Go Discharge = (2.72*Difference in Drawdowns*Aquifer Constant)

Discharge given Difference between Modified Drawdowns Formula

Discharge = (2.72*Difference in Drawdowns*Aquifer Constant)
Q = (2.72*Δs*T)

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.
