1) One 6” line (with 2 nos. of 4” nozzles) coming from air cooler to water cooler provided with anchor before the water cooler

Other 4” line going to suction drum that anchored before that drum, (this 4” line coming from 6” line nozzle from discharge drum. this also anchored)

In between these two lines I provided 4” bypass line, 60’ length
555 psig 180 degree f

Air cooler -565 psig 265degree f
Discharge drum – 565 psig 155 degree f

I completed data feeding, and successfully generated the report.

Plz suggest what are the load cases I have to consider, and is it required to consider initial displacement for all nozzles.

Can u tell how can I calculate initial displacement?
