Richard Ay,

i have continued my work on water hammer.

I would like to know how i have to enter "my" Force-Time to the DLF Specturm.

From Node 2190 to 2150 i do consider entering this parameters.



t [ms] - Force [kN]

0 - 0
10000- 85.285
10110- 0

My closure time of the the valve is 10000 ms.

My estimated rise Time is 10000 ms and my fall time is 110 ms.

Furthermore I'm not sure if i have to use the maximum force because the duration time for this leg is about 5 ms.

Do I have to change my parameters?


I add my C II files and my Force Time graph from an Excel Data.



Cheers Michael
