Sampling System

Several kinds of pipe flow calculations can be made with the Darcy- Weisbach equation and the Moody friction factor. These calculations can be conveniently carried out with an Excel spreadsheet. Many of the calculations require an iterative solution, so they are especially suitable for an Excel spreadsheet solution. This course includes discussion of the Darcy- Weisbach equation and the parameters in the equation along with the U.S. and S.I. units to be used. Example calculations and sample Excel spreadsheets for making the calculations are also included. This course is intended primarily for civil engineers, mechanical engineers, chemical engineers, and environmental engineers. After completing this course you will be able to make calculations with the Darcy Weisbach equation and the Moody friction factor equations to calculate several different unknown parameters when sufficient input data is provided. You will also be prepared to use Excel spreadsheets to efficiently make the calculations.

SA Water is responsible for operation and maintenance of an extensive network of buried pipelines. Cathodic Protection (CP) is applied to a large proportion of those buried assets which assists with the management of external pipeline corrosion and is therefore and an important asset management tool to greatly increase asset life. This Standard has been developed to assist in the design, maintenance, construction, and management of SA Water’s pipeline CP infrastructure. The purpose of this Standard is to detail the requirements for each phase of a pipeline CP project from design, construction and commissioning, to maintenance and monitoring to ensure a consistent approach is achieved independent of the delivery model of a project, its location, project ownership or other influences.

➢The amount of fluid flow through the pipeline is one of the first items of information required for design ➢ Different industries use pipeline for different purposes. requirements & types of pipe are different ➢ Petroleum industry & natural gas industry use steel pipe with welded joints. ➢ This allows the pipeline to withstand very high pressure, sometimes above 3000 psig ➢ High pressure allow the use of long pipelines, often more then 1000 miles with only a booster pump or station for each pipeline ➢ Some pipelines are designed with some excess capacity or design so capacity can be increased by the addition of compression or pumping horsepower

This course is about measurement of the flow rate of a fluid flowing under pressure in a closed conduit. This course is intended primarily for mechanical, civil and chemical, environmental, and industrial engineers. Someone completing this course will gain knowledge about twelve different types of meters for measuring fluid flow rate in a closed conduit. They will learn about typical calculations for differential pressure meters and pitot tubes. They will learn the general principles of operation for each type and general advantages and disadvantages of each.
