The velocity distribution for the stars of different masses in the typical open cluster was calculated, the velocity variations having been considered as a purely discontinuous random process. the comparison of calculated and observed mean square velocities for the different groups of stars in the Hyades cluster enables us to estimate the mean mass of the stars in the each group.
