Pressure Transients in Water Engineering: A Guide to Analysis and Interpretation of Behaviour

This book starts with an explanation of the phenomenon of pressure transients and how they may arise. It then gives an analysis of the constraints on the magnitude of transient pressures and the need for surge alleviation measures. Equations describing transient motion in pipelines are shown in a straight-forward manner and these are used to introduce the reader to some practical methods of computer analysis in use today. Case studies and assessments of systems and equipment.

The author examines a range of case studies involving different types of systems and the types of surge suppression equipment which may be suited to each. Chapters are devoted to various aspects of pipelines which can have a bearing upon pressure transient behaviour. These include flexible pipeline systems and more complicated networks that involve branching and looped pipelines. The presence of air or gas within a system is also dealt with along with considerations for the development of persistent oscillations. Practical, descriptive and enlightening.

This practical book provides an indepth analysis of actual systems, with emphasis on the type of hydraulic transient behaviour to be expected in each kind of configuration. Mathematical treatment is covered in a straightforward manner without the need to rely on advanced mathematical skills. Thus, the descriptive nature of this book allows the reader to understand behaviour without constant reference to equations.

Due to his extensive experience and insight, the author highlights various pitfalls and provides ideas on when the physical extent of a study can be truncated. Where possible simplified equations are presented to enable rapid assessment of surge equipment capacities – such as those used for pressure vessels, feeder tanks and buffer tanks.
