Anchor force interpretaion for vertical pipes - SUS case

Hello,

Please consider a piping configuration as below.

Vertical pipe connects with a horizontal vessel nozzle.
fluid is water with density of 1000 Kg/cu.m

If we model the system as Anc (with disp.) at vessel nozzle, the anchor forces (especially 'Fy') in SUS load case at Anc node includes the water weight also.
But in reality it willnot be the case.

There are many systems, where pipes with considerable fluid density drops near the vessel by 2 to 4 meters and connects with nozzle.

Can somebody explain how to interprete the result at ANC in such conditions.

Thanks in advance

I think this is similar to a top discharge pump piping..You can select the vertical portion of the pipe directly above the nozzle and change the specific gravity to zero...

Regards,

I am not able to get what exactly you mean.Can you please explain it so that we also learn from your experience.

It is correct to zero the density in a case like a vertical run off a pump for statics, but if contents weight is significant and you are doing dynamics, the fluid mass needs to be there.

Thank you very much Mr. Borzki and Mr. Moverz.

Mr Moverz,

In dynamic analysis, Will the Density have impact in vertical force ?
If so,is it correct to zero the density in static analysis? especialy for fluid like water.

Could you please clarify
Thanks again

Are you trying to qualify the nozzle load? The method explained above is acceptable.
