Supersonic Velocity in Flare Line
Supersonic Velocity in Flare Line
(OP)
If we consider a PSV as a converging diverging nozzle with sonic velocity in the throat and the outlet pressure being lower than the throat pressure, is it possible to experience supersonic velocities in the outlet line? I.e. in the same way as a Laval Nozzle.
This question has been bugging me for some time.
Thanks

sonic conditions can indeed occur in the vent line. real possibility in hp pipeline psv's and hp steam psv's

As hfgnick pointed out:
"However since the pipe is an imperfect diverging nozzle there will be tremendous loss of energy due to internal fluid friction that will reduce the flow to sonic"
I tend to agree with this statement, thanks for your input.
