1. What is Fitting Friction Loss?

Fitting friction loss refers to the energy loss that occurs when fluid flows through pipe fittings (elbows, tees, valves, etc.) due to turbulence and changes in flow direction. It's an important factor in hydraulic system design.

2. How Does the Calculator Work?

The calculator uses the friction loss equation:

Where:

• \( K \) — Loss coefficient (dimensionless)
• \( v \) — Velocity of fluid (m/s)
• \( g \) — Gravitational acceleration (9.81 m/s²)

Explanation: The equation calculates the head loss in meters of fluid column based on the fitting's resistance coefficient and the fluid velocity.

3. Importance of Friction Loss Calculation

Details: Accurate friction loss calculation is crucial for proper pump selection, system design, and ensuring adequate flow rates throughout piping systems.

4. Using the Calculator

Tips: Enter the loss coefficient (K) for your specific fitting and the fluid velocity. Typical K values range from 0.3 for long-radius elbows to 10.0 for globe valves.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find K values for different fittings?
A: K values are typically found in engineering handbooks or manufacturer specifications for specific fittings.

Q2: Does this account for pipe friction loss?
A: No, this only calculates losses through fittings. Pipe friction requires the Darcy-Weisbach equation.

Q3: How does velocity affect friction loss?
A: Loss increases with the square of velocity - doubling velocity quadruples the friction loss.

Q4: Can this be used for any fluid?
A: Yes, as long as the K value is appropriate for the fluid and flow conditions.

Q5: What are typical friction loss values?
A: For water systems, fitting losses typically range from 0.1 to 2 meters, depending on fitting type and flow velocity.
