For some, the term, water hammer, evokes images of broken and bent piping, multi-million dollar damages, the loss of water supplies to cities, and the deaths of individuals due to accidents.  Water hammer may be defined as an extreme fluid transient, occasionally recognized by loud banging, or hammering sounds, sometimes associated with fluid transients, which are caused by flow rate changes and resultant pressure surges.  Often, fluid transient and water hammer are used interchangeably.

The primary purpose of this course is to provide practicing engineers with the analytical tools required to identify water hammer concerns and prevent equipment damage, personnel injury, and fatalities.  The principles of pipe system design, with respect to fluid mechanics, valves, and pump operations are followed by basic structural piping design principles, water hammer theory, pipe system dynamics, and failure analysis.

Overall, this course integrates multiple engineering disciplines to teach the principles of troubleshooting pipe systems for fluid flow problems and pipe failures.  Since this class provides an extensive study of different engineering topics, numerous class exercises are performed to augment the presentation.

Each student will receive a copy of the book, Fluid Mechanics, Water Hammer, Dynamic Stresses, and Piping Design, and its supplement, both by Robert Leishear.

You will learn to:
 - Explain the fundamentals of fluid mechanics in pipe systems.
 - Describe the fundamentals of water hammer.
 - Explain the fundamentals of pipe failures.
 - Describe the fundamentals of dynamic pipe system response.
 - Apply corrective actions for pipe failures.

Special Requirements:
Students are required to bring calculators to the course.  The instructor recommends that they bring laptops as well.

Robert Allan Leishear, Ph.D., P.E., is an ASME Fellow and a Consulting Engineer for Leishear Engineering, LLC. His studies and accomplishments focused on fluid flow, piping design, vibrations, failure analysis, and fluid machinery, as well as explosions in piping systems. He has extensive experience in research, design engineering, test engineering, and plant engineering. Dr. Leishear has taught troubleshooting courses on vibration analysis, pumps, piping and fluid mechanics to his colleagues to ensure safety and cut costs by analyzing and preventing failures of plant machinery and piping systems. He has served on several ASME Committees, and is currently a member of the ASME B31.3 Committee Subgroup on Design, the ASME B31 Mechanical Design Committee, the ASME Section VIII Task Group on Impulsively Loaded Vessels, and the B31.3 Process Piping Committee.

Dr. Leishear earned his B.S. in Mechanical Engineering from the Johns Hopkins University, and both his Master’s and Doctorate in Mechanical Engineering from the University of South Carolina. Currently, he is matriculating in the University of South Carolina’s Ph.D. program for Nuclear Engineering. Dr. Leishear has also written more than fifty research publications, which includes the ASME text book, "Fluid Mechanics, Water Hammer, Dynamic Stresses, and Piping Design." From this work, he has earned a dozen corporate awards, several ASME Awards for Service, and the Mensa Copper Black Award for Creative Achievement.
