45 deg lateral vs 90 deg branch - which has higher sif ?
FEA using NozzlePro & FESIF shows 45 deg lateral branch is having lower SIF than 90 deg branch.
Many US design firms consider 45 deg branch SIF as 1.5 times 90 deg branch SIF; CODETI takes 1.68 times.
Now, 45 deg branch is non-code item - we need to depend on FEA; is CODETI or US design firms wrong or FEA results wrong ?
