pressure far field boundary condition

Hey, I am investigating the flow in a turbine with only one stator. For the outlet I would like to set a pressure far field BC, because I don't now the static pressure in the outlet. For this I have extended my domain length by 20 times the chord length of the blade. So how can I set this BC, with the Bc external for the outlet ? Iam using Omnis v2,
thx

If you know the throat area you can get the flow that can pass through, using that formula.

Or you can just apply different levels of pressure at the outlet until the nozzle is choked and get the operating range of the nozzle.

Unfortunately i dont know the throat area. Ah you mean i use different static pressures in the outlet, until i have mach number 1 in the outlet of the turbine ? I just investigate a turbine, without an nozzle
