Hey guys,
does anyone know which relation FLUENT uses to calculate the RH of moist air at a given temperature?
Also can i use the inbuilt formula/method fluent uses to calculate RH at a given temp ?

hey there . i found one more realtion for temperature range < 650 k (IAPWS standards) around .. however the results of RH calculation from fluent and IAPWS formulas at a given mf and temp vary too much.
Anyone can plz help .. with what exactly FLUENT does with respect to this? or where Im committing possible errors???: confused:

hey there found the prb ...
i was mistaking mass_fraction used by fluent as humidity ratio!
IAPWS formation matches with FLUENTS RH calc within 5% relative error (Given a temperature and mass fraction u calc RH from it).. i guess thats not bad

Any better methods suggestion here after are so so welcome
gd thnx
