Hi all,

I wanted to know about the multiplier to be used for the nozzle forces & moments in API 661 in Ceasar II.

the table 4 values in API 661 can be taken as 3 times for a single header.
for combined inlet & outlet nozzles.

any reply on this will be highly appreciated.

Most of the time we use multiplication factor 3 for API 661, obviously it is subjected to vendor approval.
