Discharge given Aquifer Constant Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge = Aquifer Constant/((1)/(2.72*(Drawdown in Well 1-Drawdown in Well 2)))
Q_w = T/((1)/(2.72*(s₁-s₂)))
This formula uses 4 Variables

Variables Used

Discharge - (Measured in Cubic Meter per Second) - Discharge refers to the volume of water that flows through the aquifer over a given period.
Aquifer Constant - Aquifer Constant refers to the product of the hydraulic conductivity (K) and the thickness (b) of an aquifer and also known as coefficient of transmissibility.
Drawdown in Well 1 - (Measured in Meter) - Drawdown in Well 1 refers to the reduction in water level caused by pumping in a well.
Drawdown in Well 2 - (Measured in Meter) - Drawdown in Well 2 refers to the reduction in water level caused by pumping in a well.

STEP 1: Convert Input(s) to Base Unit

Aquifer Constant: 24.67 --> No Conversion Required
Drawdown in Well 1: 2.15 Meter --> 2.15 Meter No Conversion Required
Drawdown in Well 2: 2.136 Meter --> 2.136 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_w = T/((1)/(2.72*(s₁-s₂))) --> 24.67/((1)/(2.72*(2.15-2.136)))

Evaluating ... ...

Q_w = 0.939433599999986

STEP 3: Convert Result to Output's Unit

0.939433599999986 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.939433599999986 ≈ 0.939434 Cubic Meter per Second <-- Discharge

< Discharge And Drawdown in Well Calculators

Drawdown in Well 1 given Aquifer Constant

Go Drawdown in Well 1 = Drawdown in Well 2+((Discharge*log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),10))/(2.72*Aquifer Constant))

Drawdown in Well 2 given Aquifer Constant

Go Drawdown in Well 2 = Drawdown in Well 1-((Discharge*log((Radial Distance at Observation Well 2/Radial Distance at Observation Well 1),10))/(2.72*Aquifer Constant))

Drawdown in Well 1 given Thickness of Aquifer from Impermeable Layer

Go Drawdown in Well 1 = Thickness of Aquifer-Depth of Water in Well 1

Drawdown in Well 2 given Thickness of Aquifer from Impermeable Layer

Go Drawdown in Well 2 = Thickness of Aquifer-Depth of Water in Well 2

Discharge given Aquifer Constant Formula

Discharge = Aquifer Constant/((1)/(2.72*(Drawdown in Well 1-Drawdown in Well 2)))
Q_w = T/((1)/(2.72*(s₁-s₂)))

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.

How to Calculate Discharge given Aquifer Constant?

Discharge given Aquifer Constant calculator uses Discharge = Aquifer Constant/((1)/(2.72*(Drawdown in Well 1-Drawdown in Well 2))) to calculate the Discharge, Discharge given Aquifer Constant formula is defined as a measure of the rate of flow of water from a confined aquifer, which is a vital parameter in groundwater studies, helping to understand the aquifer's capacity to supply water to wells and springs. Discharge is denoted by Q_w symbol.

How to calculate Discharge given Aquifer Constant using this online calculator? To use this online calculator for Discharge given Aquifer Constant, enter Aquifer Constant (T), Drawdown in Well 1 (s₁) & Drawdown in Well 2 (s₂) and hit the calculate button. Here is how the Discharge given Aquifer Constant calculation can be explained with given input values -> 0.939434 = 24.67/((1)/(2.72*(2.15-2.136))).

FAQ

What is Discharge given Aquifer Constant?

Discharge given Aquifer Constant formula is defined as a measure of the rate of flow of water from a confined aquifer, which is a vital parameter in groundwater studies, helping to understand the aquifer's capacity to supply water to wells and springs and is represented as Q_w = T/((1)/(2.72*(s₁-s₂))) or Discharge = Aquifer Constant/((1)/(2.72*(Drawdown in Well 1-Drawdown in Well 2))). Aquifer Constant refers to the product of the hydraulic conductivity (K) and the thickness (b) of an aquifer and also known as coefficient of transmissibility, Drawdown in Well 1 refers to the reduction in water level caused by pumping in a well & Drawdown in Well 2 refers to the reduction in water level caused by pumping in a well.
