When Bernoulli's equation holds, we can say that the static pressure is proportional to the velocity squared. We could instead say speed squared because we only need the magnitude of the velocity vector.

Therefore, an acceleration that only changes the direct of the velocity vector (i.e. centripetal acceleration) does not change the static pressure.
