1. What is Gas Pipeline Capacity?

Gas pipeline capacity refers to the maximum amount of gas that can flow through a pipeline under specific conditions. It depends on the pipeline diameter, gas velocity, and gas density.

2. How Does the Calculator Work?

The calculator uses the gas pipeline capacity equation:

Where:

• \( Diameter \) — Pipeline internal diameter (m)
• \( Velocity \) — Gas flow velocity (m/s)
• \( Density \) — Gas density (kg/m³)

Explanation: The equation calculates the mass flow rate of gas through a circular pipeline by multiplying the cross-sectional area by velocity and density.

3. Importance of Pipeline Capacity Calculation

Details: Accurate capacity calculation is crucial for pipeline design, operation optimization, and ensuring safe and efficient gas transportation.

4. Using the Calculator

Tips: Enter pipeline diameter in meters, gas velocity in meters per second, and gas density in kg/m³. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical gas velocity in pipelines?
A: Typical velocities range from 5-20 m/s, depending on pipeline size and gas pressure.

Q2: How does temperature affect capacity?
A: Temperature affects gas density - higher temperatures decrease density and thus capacity for a given pressure.

Q3: What units are used in the calculation?
A: The calculation uses SI units: meters for diameter, m/s for velocity, and kg/m³ for density.

Q4: Can this be used for liquid pipelines?
A: Yes, the same fundamental equation applies to liquid pipelines, though density values will differ.

Q5: How accurate is this calculation?
A: This provides theoretical maximum capacity. Actual capacity may be lower due to friction, elevation changes, and other factors.
