eSKa is on a distinguished road
Hello,

I´ve got problems with the calculating of the force of my fan (metro).
F= massFlow * velocity

areaAve(Velocity w)@Outlet ---40,79 m s^-1

massFlow()@Outlet ---60,07 kg s^-1

massFlow()@Outlet * areaAve(Velocity w)@Outlet ---2450,37 N

force_z()@Outlet --- 2254,37 N

I´m wondering about the difference of 200N. It would be great to know how the expression force_z()@ is defined.
There is no hint in de Ansys Post manual, or something else in the internet.

Can me pls someone help

Thanks


eska
