Any decrease in flow velocity downstream the PSV nozzle must give rise to reaction forces, F = d(mv)/dt. This will also apply for a bend, where the velocity changes direction.
So for a "black box" with a PSV arrangement inside, the net force on the system should be equal to the...
Dear Sirs,
As a structural engineer I've been assigned to design a support platform for 2 off Block Body PSVs on an offshore gas processing platform.
Downstream each PSV there is a short horizontal section, continuing via a 90 deg elbow downward to a connection to the flare header via a...
