tems affected by water hammer are usually reluctant to pass on information about any surge damage suffered.
But studying the photos taken of some “acci-dents” (Figs. 1-a, 1-b, 1-c) one thing is clear: the damage caused by water hammer by far exceeds the cost of preventive analysis and surge control measures.

book, not just water, in pipe systems. It follows on from the authors' previous monograph on the problems and solutions of water. Water hammer, or the study of fluid transient behaviour, is one of the most common problems in the water engineering community.
This book covers the many causes and solutions in a practical way and is an essential reference for all those concerned with the flow of liquids, not just water. The analysis of this type of water hammer is normally accomplished by the use of impedance methods (complex algebra), as the phenomenon is similar to the alternating current in electrical circuits.
There are those who have published widely on this topic such as Chaudhry (), Wylie (), and Thorley (), whereas Sharp () included. HAMMER is a free program I used a few years ago to simulate water hammer in a water pipe.
From HAMMER read me file: HAMMER is a program which simulates the effects of water hammer in a reservoir and pipeline system in which a valve at the. The most amazing thing about the book is that it was done in the mid's and is still up-to-date, because from that time on the waterhammer analysis has evolved not so much in the prevention and estimation aspects but in the computational one.

Where crack propagation in welds and material due to water hammer loads is a concern, use the following rules: A very high number of natural frequencies must usually be included in the analysis. Cutoff frequencies of Hz are not unusual.
These are the axial natural modes of the pipe between the excited elbow-elbow pairs. These transient events are known generally as water hammer, but as this phenomenon can happen with any liquid, other terms are fluid hammer, dynamic pressure surge or hydraulic transients.
This potentially dangerous phenomenon can be mitigated with good design practice and a hydraulic transient analysis. Additional Physical Format: Online version: Parmakian, John. Waterhammer analysis. New York, Prentice-Hall, (OCoLC) Document Type: Book.

LIQT transient analysis software for water hammer analysis provides analytical intelligence to help operators and engineers design pipe networks to avoid catastrophic events caused by pump failures and valve operations.
Transient events can be managed by provisioning of surge equipment with LIQT software. Read more. Then, the sensitivity analysis in negative and positive pressures by changing some variables such as pipe diameter, pipe length and also wave velocity in pipe was investigated.
Numerical simulation is based on characteristic method. Sensitivity analysis help designers to have well understand of water hammer Cited by: 2. Pipe Surge is state-of-the-art water hammer analysis software. Surge provides an advanced graphical interface and an easy transition between steady state and transient flow modeling.
Forty years of extensive development brings this integrated transient analysis program that includes numerous advanced features and blazingly fast analysis. Water Hammer is a pressure surge or wave that occurs when there is a sudden momentum change of a fluid within an enclosed pipeline system.
This commonly occurs in pipelines when a valve is closed suddenly at the end of a pipeline where the velocity of the fluid is high. Buy Waterhammer Analysis by John Parmakian online at Alibris.

Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid, usually a liquid but sometimes also a gas, in motion is forced to stop or change direction suddenly; a momentum change.
This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.
In Water Hammer, Valve maintenance. The analysis of the water hammer due to valve operation is a simulation which can not provide for the wear and tear that will seriously modify the valve in continued use. It is probably non-use that is as serious as any other factor in the necessity for a constant awareness of the valve condition.
