How to Calculate and Solve for Total Load on Flexible Pipe | Irrigation Water Requirement

The image above represents the total load on the flexible pipe. To calculate the total load on flexible pipe, three essential parameters are needed, and these parameters are the Load Co-efficient for Ditch Conduits (Cd), Unit Weight of Fill Material (w), Outside Diameter of the Conduit (Bc), and Width of Ditch at the Top of Conduit (Bd).

The formula for calculating Total Load on Flexible Pipe:

W_c = C_dwB_cB_d

Where:

W_c = Total Load on Flexible Pipe
C_d = Load Co-efficient for Ditch Conduits
w = Unit Weight of Fill Material
B_c = Outside Diameter of the Conduit
B_d = Width of Ditch at Top of Conduit

Let’s Solve an example;
Find the total load on flexible pipe when the load co-efficient for ditch conduits is 3, the unit weight of fill material is 5, the outside diameter of the conduit is 7 and width of ditch at top of conduit is 5.

This implies that;

C_d = Load Co-efficient for Ditch Conduits = 3
w = Unit Weight of Fill Material = 5
B_c = Outside Diameter of the Conduit = 7
B_d = Width of Ditch at Top of Conduit = 5

W_c = C_dwB_cB_d
Then, W_c = (3)(5)(7)(5)
W_c = 525

Therefore, the total load on flexible pipe is 525.

Calculating the Load Co-efficient for Ditch Conduits when the Total Load on Flexible Pipe, the Unit Weight of Fill Material, Outside Diameter of the Conduit and the Width of Ditch at Top of Conduit are Given

C_d = ^W_c / _{w x Bc x Bd}

Where;

C_d = Load Co-efficient for Ditch Conduits
W_c = Total Load on Flexible Pipe
w = Unit Weight of Fill Material
B_c = Outside Diameter of the Conduit
B_d = Width of Ditch at Top of Conduit

Let’s Solve an example;
Find the load co-efficient for ditch conduits when the total load on flexible pipe is 40, the unit weight of fill material is 4, the outside diameter of the conduit is 6 and the Width of ditch at top of conduit is 2.

This implies that;

W_c = Total Load on Flexible Pipe = 40
w = Unit Weight of Fill Material = 4
B_c = Outside Diameter of the Conduit = 6
B_d = Width of Ditch at Top of Conduit = 2

C_d = ^W_c / _{w x Bc x Bd}
C_d = ⁴⁰ / _{4 x 6 x 2}
So, C_d = ⁴⁰ / ₄₈
C_d = 0.83

Therefore, the load co-efficient for ditch conduits is 0.83.

Solve the Unit Weight of Fill Material when the Total Load on Flexible Pipe, the Load Co-efficient for Ditch Conduits, Outside Diameter of the Conduit and the Width of Ditch at Top of Conduit are Given

w = ^W_c / _{Cd x Bc x Bd}

Where;

w = Unit Weight of Fill Material
W_c = Total Load on Flexible Pipe
C_d = Load Co-efficient for Ditch Conduits
B_c = Outside Diameter of the Conduit
B_d = Width of Ditch at Top of Conduit

Let’s Solve an example;
Find the unit weight of fill material when the total load on flexible pipe is 62, the load co-efficient for ditch conduits is 2, outside diameter of the conduit is 8 and the width of ditch at top of conduit is 4.

This implies that;

W_c = Total Load on Flexible Pipe = 62
C_d = Load Co-efficient for Ditch Conduits = 2
B_c = Outside Diameter of the Conduit = 8
B_d = Width of Ditch at Top of Conduit = 4

w = ^W_c / _{Cd x Bc x Bd}
Then, w = ⁶² / _{2 x 8 x 4}
w = ⁶² / ₆₄
w = 0.96

Therefore, the unit weight of fill material is 0.96.

Solve the Outside Diameter of the Conduit when the Total Load on Flexible Pipe, the Load Co-efficient for Ditch Conduits, the Unit Weigth of Fill Material and the Width of Ditch at Top of Conduit are Given

B_c = ^W_c / _{Cd x w x Bd}

Where;

B_c = Outside Diameter of the Conduit
W_c = Total Load on Flexible Pipe
C_d = Load Co-efficient for Ditch Conduits
w = Unit Weight of Fill Material
B_d = Width of Ditch at Top of Conduit

Let’s solve an example;
Find the outside diameter of the conduit when the total load on flexible pipe is 30, the load co-efficient for ditch conduits is 14, the unit weight of fill material is 10, the width of ditch at top of conduit is 8.

This implies that;

W_c = Total Load on Flexible Pipe = 30
C_d = Load Co-efficient for Ditch Conduits = 14
w = Unit Weight of Fill Material = 10
B_d = Width of Ditch at Top of Conduit = 8

B_c = ^W_c / _{Cd x w x Bd}
That is, B_c = ³⁰ / _{14 x 10 x 8}
B_c = ³⁰ / ₁₁₂₀
B_c = 0.026

Therefore, the outside diameter of the conduit is 0.026.

Calculating the Width of Ditch at Top of Conduit when the Total Load on Flexible Pipe, Load Co-efficient for Ditch Conduits, the Unit Weight of Fill Material and Outside Diameter of the Conduit are Given

B_d = ^W_c / _{Cd x w x Bc}

Where;

B_d = Width of Ditch at Top of Conduit
W_c = Total Load on Flexible Pipe
C_d = Load Co-efficient for Ditch Conduits
w = Unit Weight of Fill Material
B_c = Outside Diameter of the Conduit

Let’s Solve an example;
Find the width of ditch at top of conduit when the total load on flexible pipe is 72, the load co-efficient for ditch conduits is 3, the unit weight of fill material is 4 and the outside diameter of the conduit is 10

This implies that;

W_c = Total Load on Flexible Pipe = 72
C_d = Load Co-efficient for Ditch Conduits = 3
w = Unit Weight of Fill Material = 4
B_c = Outside Diameter of the Conduit = 10

B_d = ^W_c / _{Cd x w x Bc}
Then, B_d = ⁷² / _{3 x 4 x 10}
B_d = ⁷² / ₁₂₀
B_d = 0.6

Therefore, the width of ditch at top of conduit is 0.6.
