Explanations of equations and introduction to computer analysis. 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.
