With converging and diverging nozzles I believe 7 degrees is ideal.
There are companies that sell 7 degree reducers for intake and exhaust piping, they are kind of expensive.

I picked up a 304 stainless steel 3 to 4 inch reducer pipe used in a water pumping system to be part of my diesel suburbans new exhaust. It has about a 12 degree slope. Not perfect but since it was free I cant argue. (had a welding defect and could not be used in the high pressure RO system it was intended for)
