Fundamentals and Analysis of Gas Pipeline Hydraulics- General Gas Flow Equation

Friction Gradient & the Moody Chart in Pipeline Pressure Drop Calculations

A comprehensive walkthrough of the general gas flow equation, commonly used in the gas transmission industry for design calculations and operations analysis. The snippet explains how the equation, derived from the Colebrook-White approximation, is used to calculate the gas flow rate under standard conditions of pressure and temperature. Key parameters such as inlet and outlet pressures, pipeline dimensions, friction factor, gas gravity, and compressibility are discussed in detail. The video also illustrates the use of the transmission factor as an alternative approach to solving the gas flow equation. This content is essential for pipeline engineers and students focused on accurately sizing pipelines and analyzing flow rates in gas transmission systems.
