Hi everyone,
It has been my practiced to neglect the reaction load for pressure safety valves of liquid lines. But in this case, I have a rupture disk that is high pressure lines working around 25mPa.
I was searching for the correct formula of thrust load for rupture disk with liquid services but sad to say I found nothing. Even here I didn´t find any.
As I understand, The reaction equation and/or condition should be similar to the equation of the

I don’t believe that the reaction load for rupture disk is equal to Pressure*Area for the liquid service. My reason is, liquid is nearly incompressible and with a slight volume change, my pressure drop rapidly.
The process would like to calculate this stuff using the Pressure heads and I feel that this is outrageous. Having in mind with the mass balance.
If my idea is incorrect, please correct it. Also I need references to support this information.
Thank you and regards
