Course overview
The Pipeline Toolbox is home to many tools and calculators. The PLTB User’s Guide presents information, guidelines and procedures for use during design, and operations tasks for field or office applications.

Several equations are available that relate the liquid flow rate with fluid properties, pipe diameter and length, and upstream and downstream pressures. In addition, two other equations are primarily used for calculating pressure drops and flow rates.


This user guide will discuss each of these equations, their limitations, and their applicability.
