  Water hammer — a high-pressure surge or wave created by the kinetic energy of the moving liquid — is not only a system issue, but primarily a safety concern. Understanding the nature and severity of water hammer in a steam-and-condensate system will allow prevention of its destructive forces. A better understanding will also help with the introduction of preventative measures into system...
