Thanks for your answers!
My main issue is to get the physical understanding of why Rhov2 is used as design criteria in flare systems.
I have worked with flare systems for 6 years (simulations, design, Norsok P-001, P-100, API 520, API521, Flarenet, Acoustic Fatigue, etc)
But still, I don't...
Rhov2 is a design limit for offshore flare systems in NORSOK P-001
But why is Rhov2 used?
NORSOK P-001 has the limit Rhov2 < 200000 kg/m/s2
What will physically happen if the limit is exceeded?
My knowledge far:
the momentum G =rho*v2
the dynamic pressure Pdynamic = rho*v2/2 by Bernoulli's eq...
