Steam Drum PSV Inlet losses
Steam Drum PSV Inlet losses

Facing similar problem:
While calculating pressure losses (unrecoverable) at PSV inlet (must be less than 3%) ...We have a straight line from steam drum nozzle & PSV is attached via reducer. So X3 components friction losses are to be considered. Question is I will include entrance losses at nozzle but will I include exit losses from reducer?
I believe exit losses after reducer will not be included ...because that entails assuming steam is exiting to atmosphere that will be a huge loss abrogating 3% rule

In my openion, since the PSV will be located immediately downstream of reducer, we must consider Total pressure loss since pressure recovery is not possible downstream of reducer.
