Hi Latexman,
I have finally found the error in my calculations.
For Direct Integration, if you have subcritical flow, I just need to step back the pressure up to the back pressure of the PSV and quote the Mass flux and calculate the area based on that mass flux rather than find the maximum...
Hi Latexman,
Thank you for the reply.
I probably haven't made the point clear.
It's perhaps misleading of me to say that Leung's omega has anything to do with critical or non-critical flow.
API method of Leung's omega details calculation of Mass Flux, G which depends on whether the flow is...
Dear all,
I have recently been asked to size 2-phase relief PSV.
Based on recent, API 520 two methods were available depending on the degree of rigorous-ness.
For quick and dirty method, Leung's 2-point Omega and for rigorous, direct integration.
Comparisons of two methods agree very well when...
