Liquid PSV thrust load

Hi,

I used the Relief Load Synthesis to calculate the thrust force for a liquid PSV. The computed mass flow rate is different with the flow rate provided by the data sheet.

Does anybody know what equations CAESAR uses for the mass flow and thrust force calcualtions?

Thanks,

See this earlier post, on the same subject.

I cannot find the paper "ASME Publication 75-WA/FE "Steam Flow through Safety Valve Vent Pipes" by H. E. Brandmaier and M. E. Knebel. " on ASME's website or anywhere else

Any idea where to get a copy of it?

Thanks,

See the attachment in my post
