1) HTRI is only for thermal design of h.e. not a mechanical design. it doesnt care about design condition. while u run HTRI it wont ask you design pre/temp. yes but in HTRI output u will see a mechanical design pres/temp. which is a default value.

2) ur question is not clear what exactly u wanted to know. be cleare

3) nozzle sizes in done by HTRI based on TEMA inlet/outlet Rho*V2 value. however u can increase the nozzle size in HTRI. just be cautious while reducing the size that you wont see vibration flags because of higher Rho*V2 value.

hope this helps

Hi expert..
I just wonder what is the maximum RVSQ for the nozzle since we do not see any vibration flag?
