Fundamentals of Waterhammer and Surge Suppression

PDH Credits: 1

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:

• Define waterhammer terminology
• Identify accidents caused by waterhammer
• Describe the four stages of waterhammer
• Understand the Joukowsky equation
• Understand the communication time concept
• Identify different types of waterhammer
• Solve fundamental equations
• Understand general principal of operation of a pulsation dampener
• Identify the types of dampeners and their pros/cons
• Describe configurations and their pros/cons
• Identify technical questions answered by waterhammer analysis
• Describe the effects of water hammer on pumps and valves 
• Explain transient cavitation 
• Describe the different methods surge can be suppressed
