About translational periodic boundary conditions in Pipe flow
 
In pressure-based solver
The periodic conditions can be specified through
mass flow rate & pressure gradient

However, I don't understand why the pressure gradient can't be really specified
I mean when I input an axial gradient
then I run the calculation
but the results won't show any axial pressure gradient

And what If I don't know the pressure gradient
and I just want the target mass flow rate
then how should I set the axial pressure gradient?
