  Hello,
  
  When I name the outlet of my nozzle I get an error in the setup saying "cannot change surface body to fluid. They are different kinds."
  
  Any suggestions on how I can fix this?

  If you're in 2d then the surface (in on the z=0 plane) can be changed to fluid type. In 3d we need a volume. Without seeing the geometry it's hard to say, but check you've created a volume and not a shell.
