Hi to all members,

I'm trying to make nozzle analysis, but I'm facing difficulties with some terminology. I can't understand how to post the center line direction cosines of the equipment and the nozzle. I'm reading the COADE guide, but the page with the picture is missing. Can someone post the page with the pictures or other illustration to imagine the problem. I will be very thankful if there is any explanation at least...:)
And one more thing - what is Ratio Rm / Ts and where should I write it?
Thanks in advance!

Nozzle Flexibility in piping input, nozzle/equipment limit checks in piping input, or WRC analysis after the run? Did you check the "help"?

Where are you looking for Rm/Ts?

Just so we're all on the same page, what Version/Build are you running?

Thank you for your fast act, Richard!

In fact I'm not sure that I'm making the wright type of analysis. I am talking about cylindrical equipment and a cylindrical nozzle. I read the help and other materials and thought that WRC 107/297 is my case. More accurate - WRC 297. By the analysis I have very big loads at a anchor, which is nozzle of the equipment. And I thought to estimate something. I admit that I do not have experience with nozzle analysis. So I start to fill the fields for WRC 297. After I submit my question here I understand that my case can not be subscribed by the WRC, because my nozzle is not perpendicular to the axis of the equipment. Is this wright?

After I read your post think that maybe I it better to make "nozzle/equipment limit checks in piping input"...I don't know exactly. Can you advise me for the wright type of analys in my case.

About the version - 5.10

About the Rm/Ts - when I did WRC 107 there was mistake that the number is 365, but the limits are 5-300.

Thank you!

Correct, WRC is for perpendicular cylinder-cylinder intersections.

The nozzle/equipment limit checks won't help you here. This is a 1st pass screening tool. If you exceed the defined limits, then you need to perform the more sophisticated analysis specific to your nozzle type.

If you're outside the scope/range of WRC, you'll need to utilize FEA.

Thank you, Richard! I was suspecting that kind of answer about FEA.
