Waterhammer Analysis By Hand

[Chris73]

Hi Eng's!
Can somebody tell me or give me link to an accepted method of doing a waterhammer analysis by hand? The situation is a sewer forcemain of app. 800m lenght between two liftstations - cont. up-slope. Especially I would like to determine the low-pressure curve over the entire pipe! Is that possible by hand? Thanks!

YEs, Before computers there were graphical techniques. The books would be long out of print now.

The book by Parmekian 1965 would have them, I think?

You could get the freeware from the US Army Corps called Whamo. It wouldnt take more time than learning the graphical method.

Try the Bergeron method described here:-
