1. What is Head Loss due to Friction?

Head Loss due to Friction occurs due to the effect of the fluid's viscosity near the surface of the pipe or duct. It represents the energy loss in a fluid flow system caused by friction between the fluid and the pipe walls.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Head Loss due to Friction = \frac{128 \times Dynamic Viscosity \times Discharge in Pipe \times Length of Pipe}{\pi \times Specific Weight of Liquid \times Diameter of Pipe^4} \]

Where:

Dynamic Viscosity — Internal resistance of a fluid to flow (Pa·s)
Discharge in Pipe — Volume of fluid passing through the pipe per unit time (m³/s)
Length of Pipe — Total length of the pipe (m)
Specific Weight of Liquid — Weight per unit volume of the substance (N/m³)
Diameter of Pipe — Diameter of the pipe in which the liquid is flowing (m)
π — Archimedes' constant (approximately 3.14159)

Explanation: This formula calculates the head loss in a pipe due to friction, considering the fluid properties and pipe dimensions.

3. Importance of Head Loss Calculation

Details: Accurate head loss calculation is crucial for designing efficient fluid transport systems, determining pump requirements, and ensuring proper system operation in various engineering applications.

4. Using the Calculator

Tips: Enter all values in the specified units. Ensure all values are positive and valid. The calculator provides results in meters of head loss.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect head loss in pipes?
A: Head loss is affected by fluid viscosity, flow rate, pipe length, pipe diameter, and pipe roughness.

Q2: How does pipe diameter affect head loss?
A: Head loss decreases significantly with increasing pipe diameter (to the 4th power), making diameter the most influential factor.

Q3: When is this formula applicable?
A: This formula is particularly applicable for laminar flow conditions in circular pipes.

Q4: What are typical units for head loss?
A: Head loss is typically measured in meters (or feet) of fluid column, representing the energy loss per unit weight of fluid.

Q5: How does fluid viscosity affect head loss?
A: Higher viscosity fluids experience greater head loss due to increased internal resistance to flow.
