1. What is Gas Velocity?

Gas velocity is the speed at which gas flows through a pipe or conduit. It's calculated by dividing the volumetric flow rate by the cross-sectional area of the pipe.

2. How Does the Calculator Work?

The calculator uses the velocity formula:

Where:

• \( Volume\ Flow \) — Volumetric flow rate (m³/s)
• \( Area \) — Cross-sectional area of the pipe (m²)

Explanation: The equation shows that velocity increases with higher flow rates or smaller pipe diameters.

3. Importance of Velocity Calculation

Details: Knowing gas velocity is essential for proper pipe sizing, avoiding erosion, ensuring efficient transport, and maintaining appropriate pressure drops in piping systems.

4. Using the Calculator

Tips: Enter volume flow in m³/s and area in m². Both values must be positive numbers. The calculator will compute the gas velocity in meters per second (m/s).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical gas velocity in pipes?
A: For natural gas, typical velocities range from 5-20 m/s depending on the application and pipe size.

Q2: Why is gas velocity important?
A: Excessive velocity can cause noise, erosion, or excessive pressure drop, while too low velocity may allow liquid accumulation.

Q3: How does pipe diameter affect velocity?
A: For a given flow rate, velocity increases as pipe diameter decreases (velocity is inversely proportional to the square of the diameter).

Q4: What's the difference between velocity and flow rate?
A: Flow rate is the volume of gas passing a point per unit time, while velocity is the speed at which the gas is moving.

Q5: Can I use this for liquids as well?
A: Yes, the same formula applies to liquid flow velocity calculations.
