Hi, everyone.When the relieving fluid is liquid is it necessary to choose the smaller one from the calculated relief rate and the normal flowrate?Thank you in advance.
Hi,
Your query isn't so clear...please explain clearly about the conditions of low and high pressure sides and the calculation you did perform to specify the relief load...

Hi, fallah,
This is a general question about the tube rupture scenario for the liquid relief.
For tube rupture scenario the fluid in high pressure side is still liquid instead of flashing. So the relief rate calculation is conducted and much higher than the normal liquid flowrate in high pressure side. My question is whether to choose the smaller data(the normal liquid flowrate) as the relief rate to size the PSV.

General question will lead to general answer...
The calculated relief load is to be considered in relevant PSV sizing even if it's higher than normal flow rate...
