We derive the pointwise estimates for the pressure in both cases. Moreover, we consider the linearized problem in a truncation domain (Formula presented.) of the exterior domain (Formula presented.) under certain artificial boundary conditions on the truncating boundary (Formula presented.), and then compare this solution with the solution in the exterior domain (Formula presented.) to get the truncation error estimate.
