Fundamentals and Analysis of Liquid Pipeline Hydraulics- Law of Energy Conservation

Applying the Law of Energy Conservation to Pipeline Pressure Loss Calculations

Here we explore the application of the law of energy conservation to calculate pressure loss in a pipeline system. By analyzing a pipeline flowing from point A to point B, we break down how the total pressure loss is determined by the friction loss, elevation change, and velocity change. Using a practical example of a 10,000-foot pipeline with a 12-inch diameter and a 5-degree upward inclination, we calculate the friction gradient, elevation gradient, and the total pressure gradient. This step-by-step guide is ideal for pipeline engineers who need to accurately predict pressure loss and optimize pipeline design by considering all critical factors such as fluid density, friction factor, and elevation changes.
