This webinar is a continuation of the Hydraulic Institute’s water hammer webinar series and encompasses three parts. The first being a review of the physics behind surge including the causes and key equations for quantifying. The second portion will guide those in attendance on when and how to evaluate a system for surge using examples from computer surge modeling. After having a general understanding of the first two portions of the webinar, an attendee will be able to better understand surge mitigation solutions and which options are more or less suitable for a particular type of surge.

In all, an overview of the following topics will be reviewed: Joukowsky Equation, wave speed, communication time, high frequency monitoring, computer modeling including a brief discussion on the differences between Method of Characteristics (MOC) and Wave Characteristics Method (WCM), low vs high pressure transients, system design changes and suppression equipment.

Key learning objectives to take away are:

  • Surge physics and common equations
  • Evaluation of surge – the when and how
  • Options for mitigating surge
    • System design changes
    • Surge suppression equipment
