Default far field for incompressible

HI all,

Fluent user's guide stated that pressure far field boundary conditions are used to model a free-stream "compressible" flow at infinity.

I need to use pressure far field BC but my flow is incompresible M=0.13.

What difference in equations does Fluent use for compressible and incompressible?

If I model the incompressible flow, how the far field BC will affect it?

Thanks in advance
