Gas Pipeline Hydraulics
This online engineering PDH course covers the steady state analysis of compressible fluid flow through pipelines. In particular, we will cover natural gas pipeline transportation including how pipelines are sized for a particular flow rate, the pressure required to transport a given volume of gas and the compression horsepower required.
The properties of natural gas that affect pipe flow will be reviewed first followed by the concepts of laminar and turbulent flow and Reynolds number. Frictional pressure loss and the method of calculating the friction factor using the Moody diagram and the Colebrook and AGA methods will be illustrated with examples. Several other popular flow equations, such as the Weymouth, IGT and Panhandle formulas will be introduced and explained with example problems. Increasing pipeline throughput using intermediate compressor stations as well as pipe loops will be discussed. The strength requirement of pipes, allowable operating pressure and hydrostatic test pressure will be reviewed with reference to the DOT code requirements.
This 6 PDH online course is intended for civil, mechanical and process engineers involved in the planning, design, and construction of gas pipelines, or seeking to gain a better understanding of the hydraulics of gas pipelines.
This P.Eng. continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding gas properties including viscosity, pressure, compressibility factor and gas laws
- Calculating the properties of a natural gas mixture
