Overview
This online course on liquid pipeline hydraulics covers the steady state transportation of liquids in pipelines. These include water lines, refined petroleum products and crude oil pipelines. This course will prove to be a refresher in fluid mechanics as it is applied to real world pipeline design. Although many formulas and equations are introduced, we will concentrate on how these are applied to the solution of actual pipeline transportation problems.
First, the liquid properties are discussed and how they vary with temperature and pressure are analyzed. The pressure in a liquid and liquid head are explained next. Then the classical Darcy equation for determining pressure drop due to friction in liquid flow is introduced and a modified more practical version is explained. Common forms of equations relating flow versus pressure drop due to friction are introduced and applications illustrated by example problems. In a long distance pipeline the need for multiple pump stations and hydraulic pressure gradient are discussed.
Next the pumping horsepower required to transport a liquid through a pipeline is calculated. Centrifugal and positive displacement pumps are discussed along with an analysis of the pump performance curves. The impact of liquid specific gravity and viscosity on pump performance is explained with reference to the Hydraulic Institute charts. The use of drag reduction as a means to improving pipeline throughput is explored. Batching of different products in a pipeline simultaneously, with minimum commingling, is discussed next. The internal design pressure in a pipeline and the hydrostatic test pressure for safe operation are explained with illustrative examples.
