Water hammer in pressure vessels
Water hammer in pressure vessels
(OP)
Hi to everybody,
Congratulations for this forum is quite usefull and interesting!
I'll post a question that arrive me today. A client made a water hammer calculation and found that a pressure vessel will be submitted to full vacuum.
Since this situation is a temporary, how should I calculate this situation?. Is this considered in the ASME Code?
Thanks in advance!

RE: Water hammer in pressure vessels
Even it will be full vacuum and is temporary, you do need to design for full vacuum. Sudden failure in vacuum will kill the vessel. No need to run the risk. Many vessels will be steamed out temporarily prior to start-up, we do design for partial vacuum due to condensation of steam.
