Dear Sirs
when you are for example performing a nozzle check as per API 610, and you need to compare the restraint summary results with the allowable loads, how do you combine the loads to get Fr and Mr?
I guess that Fr = (Fx^2 + Fy^2 +Fz^2)^1/2
What about Mr?
Sorry for the trivial question.

I would not do this manually. Use the "\Analysis\API-610" module, it will do all this for you.

It's your standard summation of moments resolved about a given point - sum the moments and multiply the forces by their moment arms to that point.

Thank you Richard.
I just want to understand, because I always use the API Tables, and I want to understand the meaning of the numbers I write in my reports.

Thank you.
I usually model the pump with a rigid + ANC with cnode between pump and pipes. So, my question is: if I don't want to use the API's module, (because for example I have to check the loads with an old version of API), is it possible for the output reports of Caesar to find the data to calculate Mr?
Do I have to read the restraint report at the ANC and calculate
Mr=(Mx^2+My^2+Mz^2)^1/2
Thank you


I'

Yes, collect the forces and moment on the pump's two nozzles and sum them. Be sure you have the loads ON the PUMP and not the loads ON the PIPE.
