How to calculate available area A5 in nozzles like Fig UG-40(g)?
(OP)
I need calculate a nozzle with a configuration similar to Fig UG-40(g) of ASME VIII Division 1.
I need to known how to calculate area A5 using te given in figure UG-40(g).
Area A5 is calculated as a rectangular area
A5 = (Dp - d - 2tn)*te*fr4 ?
Or
Area A5 is calculated as a triangular area
A5 = 0.5*te*te*tag(30)*fr4 ?

A5=te * te * tan(30) * fr1
First equation you mention is applicable where credit can be taken for additional reinforcement up to the limit defined by dimension "Dp" - not applicable in your case. Likewise "fr1" is the relevant factor as reinforcement is part of nozzle material.
