Overview

Waterhammer is a pressure surge in a piping system due to a sudden change in flow. It can occur when the power to driver is lost, air is expelled from a system, a valve closes too quickly, or a check valve slams shut. This webinar will review what can happen as a result of the waterhammer, some basic physics, and ways to account for it in your pumping system design.

Learning Objectives

Upon successful completion of this webinar, participants will be able to:
