Hi all!

It’s my first calculation with WRC297, and I have any questions about:

-If the nozzle have reinforcement pad, should you add the thickness of the shell to perform the calculations?
-If the ratio d/t≤20, is it possible consider the results as correct?
-If the ratio T/t or λ are too large , is it possible consider the results as correct?

Thank you!!

for d/t up to 10, the results are with in good approximation.

no need to add thickness of shell and pad... there is a tab avilable to insert dimensions of pad.
