Independently of the ecuation (I use to obtain T in kg, changing for that the pressure units from N/m^2 to kg/m^2), I have a given 'theoretical' thrust (from technical data), and comparing it with...

:O I completely missed this part!!! Thank you john!!.

Then , if the thrust is T=massflow/g*V2+A*(P2-P1) (since the fan is static, V1=0), and I know all variables except P2 (P1=Patm), I can solve...

I'm working in FINE/turbo with a fan blade geometry, but I'm encountering a lot of problems in finding a converged solution.

I've reviewed all properties but I'm unabled to find a...
