摘要：

The dependence of the transverse relaxation time T-2 on the liquid, flow velocity in a porous medium (for the water and water suspension of magnetic nanoparticles (MNPs)) is studied. The T-2 value allows measuring the filtration velocity of a liquid on the order of 0.05 mm/s. MNPs in a small concentration decrease T-2 but at the same time the dependence of T-2 on the liquid's velocity becomes more pronounced.
