What causes Friction Loss In Pipe?

Friction loss in fluids refers back to the discount in stress or energy of flowing fluid via a conduit like a pipe, hose, or channel. The lack of power or strain is resulting from the inner surface of the conduit.# Friction loss in fluids can be as a result of numerous factors:

• Pipe Roughness
• Flow Velocity
• Pipe Length
• Pipe Diameter
• Fluid Viscosity

The viscosity of the numerous materials is unique due to the molar weight. The calculator calculates the volumetric flow charge in step with the viscosity of a liquid.

How to Calculate Friction Loss?

You can locate frictional loss in pipes with the Hazen-Williams equation which is as follows:

\[Hf = \frac{0.2083 \cdot (L / C)^{1.852} \cdot Q^{1.852}}{D^{4.87}}\]

Where:

• Hf =  head loss due to friction
• C = Hazen-Williams friction coefficient
• L  = Length of the pipe
• Q = flow rate
• D = Internal diameter of the pipe

Friction Loss example:

A manufacturing plant is designing a cooling water system. The Pipe Diameter is \(200 \, \text{mm}\), the Pipe Length is \(500 \, \text{meters}\), and the Flow Rate is \(0.8 \, \text{m}^3/\text{s}\). Calculate the pipe friction loss using the Hazen-Williams Equation.

Given:

• Pipe Diameter (\(D\)) = \(200 \, \text{mm} = 0.2 \, \text{m}\)
• Pipe Length (\(L\)) = \(500 \, \text{m}\)
• Flow Rate (\(Q\)) = \(0.8 \, \text{m}^3/\text{s}\)

Solution:

The Hazen-Williams friction loss equation is:

\[ H_f = \frac{0.2083 \cdot \left(\frac{L}{C}\right)^{1.852} \cdot Q^{1.852}}{D^{4.87}} \]

Assuming the Hazen-Williams coefficient (\(C\)) is \(130\):

Substitute the values into the formula:

\[ H_f = \frac{0.2083 \cdot \left(\frac{500}{130}\right)^{1.852} \cdot (0.8)^{1.852}}{(0.2)^{4.87}} \]

First, calculate each term:

• \(\frac{L}{C} = \frac{500}{130} \approx 3.846\)
• \((3.846)^{1.852} \approx 9.147\)
• \((0.8)^{1.852} \approx 0.682\)
• \((0.2)^{4.87} \approx 0.000156\)

Now substitute these values back into the equation:

\[ H_f = \frac{0.2083 \cdot 9.147 \cdot 0.682}{0.000156} \]

\[ H_f = \frac{1.299}{0.000156} \]

\[ H_f \approx 8,327.28 \, \text{meters} \]

Therefore, the friction loss is approximately \(8,327.28 \, \text{meters}\).
