All my best wishes for 2016 !

In PV elite 2016, for calculation of nozzle reinforcement according to Appendix 1-10, radius Rn does not take into account the tilt angle, and thus Rn is the radius for a perpandicular nozzle for a nozzle inclined at 45deg.
Do I have to input the actual diameter? Or am I missing something?

Thank you in advance for any help,
Yann

Just to add a few: it seems that PV elite does not consider Rnc=Rn/sin teta for a nozzle with a tilt angle of 135 deG.

Hello YLV

The tilt angle is taken into account, but to see it, you must look carefully through the output report. It is a bit confusing at the beginning of the report, but the correct solution is there.

Hello Ray,
Thank you for your reply.
In the meantime I have checked the report more carefully, and I found that it was ok. I have been confused by the sentence in the code. Rnc has not to be used in formulas which concern the nozzle itself. The actual radius Rn has to be used.
