velocity source

Hello everyone. I'm pretty new to openFoam. I'm trying to create a 2D model in the follow way:

A rectangular domain spanning from x = -50.0 to 50.0 and y from -103.3 to 50.0. I am enforcing 0 velocity at this boundary. Inside the domain I have a rectangle spanning from x = -2.5 to 2.5 and y = -3.83 to -2.83, also with 0 velocity BCs. The more complicated part is I have a line (or a rectangle with 10e-6 thickness) spanning from x=-5 to 5 at y = 0. Here, I need the BC to be u = 0 and v =-5.84 going in from the top and out the bottom.

I would appreciate any advice on the best way to set this up?

After some investigation, I think maybe fan pressure may be what I'm looking for, but would love suggestions.
