Gas Pipeline Flow Analysis

Calculate gas pipeline flow rates and outlet pressures using Weymouth, Panhandle A, and Panhandle B equations.

Design Steps:

• Define pipeline geometry and gas properties
• Calculate flow capacity using each correlation
• Compare outlet pressures at fixed flow rate
• Evaluate gas velocity and Reynolds number

Equation Selection:

• Weymouth: High-pressure large-diameter pipelines, conservative
• Panhandle A: Medium-pressure transmission lines, Re > 5M
• Panhandle B: High-pressure large-diameter, fully turbulent flow

Typical Efficiency Factors:

• Weymouth: E = 1.0 (theoretical)
• Panhandle A: E = 0.92
• Panhandle B: E = 0.95
