Gas Pipeline Hydraulics

Course No. O-5001

Credit: 5 PDH

Course Fee: $139.95 Purchase course

Subject Matter Expert: E. Sashi Menon, P.E.

Overview

Gas Pipeline Hydraulics www.systek.usThis online course on gas pipeline hydraulics covers the steady state analysis of compressible fluid flow through pipelines. Mathematical derivations are reduced to a minimum, since the intent is to provide the practicing engineer a practical tool to understand and apply the concepts of gas flow in pipes. 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 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. Several fully solved example problems are used to illustrate the concepts introduced in the various sections of the course.

The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of the course to obtain PDH credits.
