For the stochastic linear transport equation with L-p-initial data (1 < p < 2) on the full space \BbbRd, we provide quantitative estimates, in negative Sobolev norms, between its solutions and those of the deterministic heat equation. Moreover, for initial data in L-p with p is an element of (root 2, 2), we establish a similar estimate between the solutions of stochastic 2D Euler equations and deterministic 2D Navier-Stokes equation in vorticity form.
