Natural Gas Pipeline Flow Calculations

The Natural Gas Pipeline Flow Calculations online PDH course is a part of the Civil Engineering category of courses.

Several different equations have been proposed and are in use for natural gas pipeline flow calculations.  This course provides information about four of them, the Weymouth Equation, the Panhandle A Equation, the Panhandle B Equation, and the Darcy Weisbach Equation, along with information about the fluid properties needed and their estimation or calculation.

This course is intended for, petroleum engineers, chemical engineers, geotechnical engineers, environmental engineers, and civil engineers.  An attendee of this course will gain knowledge about four equations used for natural gas pipeline flow equations and how to use them.

Learning Objectives

At the end of the course, you will:
