How to Calculate and Solve for Total Volume Discharge per Unit Width of Aquifer | Flow Lines

The image above represents total volume discharge per unit width of aquifer. To calculate total volume discharge per unit width of aquifer, four essential parameters are needed and these parameters are Hydraulic conductivity (k), Number of flow tubes (p), Total Head Loss over the Length of the Flow Lines (h) and Number of Squares or Equipotential Drops (f).

The formula for calculating total volume discharge per unit width of aquifer:

q^t = ^Kph / _f

Where:

q^t = Total Volume Discharge per Unit Width of Aquifer
K = Hydraulic Conductivity
p = Number of Flow Tubes
h = Total Head Loss over the Length of the Flow Lines
f = Number of Squares or Equipotential Drops

Let’s solve an example;
Find the total volume discharge per unit width of aquifer when the hydraulic conductivity is 5, the number of flow tubes is 8, total head loss over the length of the flow lines is 11 and the number of squares or equipotential drops is 13.

This implies that;

K = Hydraulic Conductivity = 5
p = Number of Flow Tubes = 8
h = Total Head Loss over the Length of the Flow Lines = 11
f = Number of Squares or Equipotential Drops = 13

q^t = ^Kph / _f
That is, q^t = ^(5)(8)(11) / ₁₃
q^t = ⁴⁴⁰ / ₁₃
q^t = 33.84

Therefore, the total volume discharge per unit width of aquifer is 33.84.

Calculating the Hydraulic Conductivity when the Total Volume Discharge per Unit Width of Aquifer, the Number of Flow Tubes, Total Head Loss Over the Length of the Flow Lines and Number of Squares or Equipotential Drops are Given.

k = ^{qt x f} / _ph

Where;

K = Hydraulic Conductivity
q^t = Total Volume Discharge per Unit Width of Aquifer
p = Number of Flow Tubes
h = Total Head Loss over the Length of the Flow Lines
f = Number of Squares or Equipotential Drops

Let’s solve an example;
Find the hydraulic conductivity when the total volume discharge per unit width of aquifer is 20, the number of flow tubes is 5, the total head loss over the length of the flow lines is 4 and the number of squares or equipotential drops is 2.

This implies that;

q^t = Total Volume Discharge per Unit Width of Aquifer = 20
p = Number of Flow Tubes = 5
h = Total Head Loss over the Length of the Flow Lines = 4
f = Number of Squares or Equipotential Drops = 2

k = ^{qt x f} / _ph
That is, k = ^{20 x 2} / _{5 x 4}
k = ⁴⁰ / ₂₀
k = 2

Therefore, the hydraulic conductivity is 2.

Calculating the Number of Flow Tubes when the Total Volume Dishcharge per Unit Width of Aquifer, the Hydraulic Conductivity, Total Head Loss Over the Length of the Flow Lines and the Number of Squares or Equipotential Drops are Given.

p = ^{qt x f} / _kh

Where;

p = Number of Flow Tubes
q^t = Total Volume Discharge per Unit Width of Aquifer
K = Hydraulic Conductivity
h = Total Head Loss over the Length of the Flow Lines
f = Number of Squares or Equipotential Drops

Let’s solve an example;
Find the number of flow tubes when the total volume discharge per unit width of aquifer is 32, the hydraulic conductivity is 7, the total head loss over the length of the flow lines is 6 and the number of squares or equipotential drops is 9.

This implies that;

q^t = Total Volume Discharge per Unit Width of Aquifer = 32
K = Hydraulic Conductivity = 7
h = Total Head Loss over the Length of the Flow Lines = 6
f = Number of Squares or Equipotential Drops = 9

p = ^{qt x f} / _kh
So, p = ^{32 x 9} / _{7 x 6}
p = ²⁸⁸ / ₄₂
p = 6.86

Therefore, the number of flow tubes is 6.86.

Calculating the Total Head Loss Over the Length of the Flow Lines when the Total Volume Discharge per Unit Width of Aquifer, the Hydraulic Conductivity, the Number of Flow Tubes and the Number of Squares or Equipotenial Drops are Given

h = ^{qt x f} / _kp

Where;

h = Total Head Loss over the Length of the Flow Lines
q^t = Total Volume Discharge per Unit Width of Aquifer
K = Hydraulic Conductivity
p = Number of Flow Tubes
f = Number of Squares or Equipotential Drops

Let’s solve an example;
Find the total head loss over the length of the flow lines when the total volume discharge per unit width of aquifer is 14, the hydraulic conductivity is 10, the number of flow tubes is 4 and the number of squares or equipotential drops is 12.

This implies that;

q^t = Total Volume Discharge per Unit Width of Aquifer = 14
K = Hydraulic Conductivity = 10
p = Number of Flow Tubes = 4
f = Number of Squares or Equipotential Drops = 12

h = ^{qt x f} / _kp
That means, h = ^{14 x 12} / _{10 x 4}
h = ¹⁶⁸ / ₄₀
h = 4.2

Therefore, the total head loss over the length of the flow lines is 4.2.

Calculating the Number of Squares or Equipotential Drops when the Total Volume Discharge per Unit Width of Aquifer, the Hydraulic Conductivity, the Number of Flow Tubes and the Total Head Loss Over the Length of the Flow Lines are Given

f = ^kph / _q^t

Where;

f = Number of Squares or Equipotential Drops
q^t = Total Volume Discharge per Unit Width of Aquifer
K = Hydraulic Conductivity
p = Number of Flow Tubes
h = Total Head Loss over the Length of the Flow Lines

Let’s solve an example;
Find the number of squares or equipotential drops when the total volume discharge per unit width of aquifer is 26, the hydraulic conductivity is 14, the number of flow tubes is 21 and the total head loss over the length of the flow lines is 17.

This implies that;

q^t = Total Volume Discharge per Unit Width of Aquifer = 26
K = Hydraulic Conductivity = 14
p = Number of Flow Tubes = 21
h = Total Head Loss over the Length of the Flow Lines = 17

f = ^kph / _q^t
f = ^{14 x 21 x 17} / ₂₆
So, f = ⁴⁹⁹⁸ / ₂₆
f = 192.2

Therefore, the number of squares or equipotential drops is 192.2.
