cfd^2 is on a distinguished road

I have known values for mass flow/velocity inlet based on a 3D model. I want to run it in Fluent usinf 2D axisymmetric solver. Do I need to convert the value of the inlet of the 3D case to the 2D axisymmetric one?

ghost82 will become famous soon enough
From fluent user guide:

Note that for axisymmetric problems, this mass flow rate is the flow rate through the entire ( -radian) domain, not through a 1-radian slice.
Also velocity (obviously) is the same.
