Ready33 is on a distinguished road

I have a simulation with cylindrical inlet (rocket engine with solid propellant). Gas flow thru surface of cylinder, so I use surfaceNormalFixedValue

type surfaceNormalFixedValue;
refValue uniform -1.1269;

But there is a problem. Velocity of inlet gas depends on actual pressure

u = u0 . p^k

where u0 and k are constant. Do you have any idea how to do it?
