Flow in a pipe with a very large aspect ratio

It's a 2-D axisymmetric model. Symmetry on the left boundary, wall on the right, inlet at the top and outlet at the bottom. The outlet is set to a zero pressure, and I have tried many different inlet boundary conditions. I started with a much smaller system, the same radius, but a length of only 8 ft which worked perfectly, but it's not working on the larger system. I feel like I'm missing something obvious.
