JORGE ORTEGA Posted May 27, 2019 Report Share Posted May 27, 2019 ¿Is there any way of simulate to obtain a value of pressure caused by water hammer? I need this for the design of shock absorver system regards Quote Link to comment Share on other sites More sharing options...
Florian Michelin Posted May 30, 2019 Report Share Posted May 30, 2019 Hi Jorge, Sorry for the delay. You can find a water hammer tool in the Tools | Calculator. The naming here could be improved. Regards, Quote Link to comment Share on other sites More sharing options...
JORGE ORTEGA Posted June 3, 2019 Author Report Share Posted June 3, 2019 Can you explain me about the value "time" , the other values are from the model... Regards Quote Link to comment Share on other sites More sharing options...
JORGE ORTEGA Posted June 3, 2019 Author Report Share Posted June 3, 2019 Another question, is the result the increment of pressure in the pipe ? Quote Link to comment Share on other sites More sharing options...
Florian Michelin Posted June 3, 2019 Report Share Posted June 3, 2019 The time is the time it takes to close the valve. The pressure is an increment so will need to be added to the normal pressure. Quote Link to comment Share on other sites More sharing options...
Felipe Silva Posted January 26, 2021 Report Share Posted January 26, 2021 Hi Florian, I would like to ask if the water hammer calculation method is the same one as Alievi and Michaud, through Mendiluce´s book. Regards Quote Link to comment Share on other sites More sharing options...
Martin Griffith Posted January 27, 2021 Report Share Posted January 27, 2021 Hi Felipe, We don't have that reference, but I think it's probably the same. Pumpsim uses the equation for slow-valve closure for incompressible flow, given at the following Wikipedia page: https://en.wikipedia.org/wiki/Water_hammer#Slow_valve_closure;_incompressible_fluid The safety factor of 5 is used. Any suggestions or feedback you have on this is welcome. Quote Link to comment Share on other sites More sharing options...
