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?
