Water Hammer and Piping Stresses
This tutorial provides guidance to help understand the causes, and to prevent or mitigate the effects of water hammer, or fluid transients, in piping and pipeline systems. The text of this paper is based on early drafts of ASME B31D, which is still under consideration (The American Society of Mechanical Engineers, ASME Code for Pressure Piping, ASME B31D, Design of Piping Systems for Dynamic Loads from Fluid Transients). Drafts of B31D were, in turn, based on an ASME Press text book, titled Fluid Mechanics, Water Hammer, Dynamic Stresses, and Piping Design which was written by this author. The information presented here is not necessarily new, but it is provided in a format to provide an overview of fluid transient topics that are important to practicing engineers who work with piping systems.
