3 - Water Hammer and Cavitation

5 - Water Hammer and CavitationWater hammer is the name given to the effect of sudden pressure changes, also known as pressure shocks, in pipelines or other equipment. The stresses caused by these shocks are typically greater than those to which the equipment is usually subjected, or in fact designed to withstand. The shock wave, which travels with the velocity of sound, can cause deformation or even breakage of system components and equipment. The occurrence of water hammer is characterised by loud banging and knocking noises from within the system pipework.

Approximate duration: 30 minutes.

By the end of this course, you should be able to:

  • Describe what water hammer is and the different types that can occur
  • Identify the possible causes and consequences of water hammer
  • Describe the basic rules to avoid the occurrence of water hammer
  • Explain what cavitation is as well as why and where it can occur
  • Identify the potential consequences of cavitation
  • State the basic rules for avoiding cavitation
