Hi,
I'm doing the check calculation per ISO 13445-3 for the reinforcing ring of the nozzle, and I'm having issues calculating the maximum lengths l0 of ring and the average thickness eam.
Firstly, there is an error in formula 9.5-47:
l0 = lr + (l0 - lr) - this makes no sense
But the l0 and eam are connected via 9.5-46 and 9.5-48, and this is not possible to calculate, or am I missing something?
Does anybody have the slightest idea how to calculate these values?
Thanks in advance!
