Not refusing to learn, it's as he says an engineering judgement. He does not know the system nor the configuration or the extent of the calculations. Thanks for the help.
I am not trying to use a design factor to cover the surge; we are already using the Joukowsky equation to predict the pressure rise in the system in an over-conservative pump start-up (i.e. void filling) scenario.
We were asked to use an additional dynamic factor on top of the predicted...
Thank you for the replies! We are trying to get by without having to resort to software (therefore the "quasi-static" approach). What I was trying to do is determine a conservative dynamic load factor (DLF) to apply to the peak force to bound impact forces due to fluid transients to convert...
Hello,
Am having some fun designing piping systems to ASME B31.3 and I have to address fluid transients. I am applying loads to the piping per code, however there is no distinction between static and dynamic loading cases or any guidance as to what a good dynamic impact factor would be for the...
Hi,
I am in the process of assisting with the design of a building that requires some personnel entry doors that need to withstand an over-pressure of 5 psi and have a 3 hour fire rating. I have done some preliminary research and found some vendors, however I am curious to know what...
