I am modelling a pipeline with reducers and nozzle connected to tank.
1. While modelling the reducer as a component with uniform dia = (dmax + dmin) / 2, where dmax = max dia of reducer and dmin = min dia of reducer, do I have to enter SIF's ?
If so, what value ?

2. Do I have to enter any SIF for the nozzle ? If so, how ?

Please help

TIA
