As a result of the collision the particles receive angular velocity, which gradually decreases with time. For numerical simulation of saltation it is necessary to know values of the drag rotation coefficient. In this paper experimental results of the rotating spherical particles moving in water are described. The rubber spherical balls with density near that of water were used; each of them was speeded up in a special chute that ensured that the particle rotated in a given plane. Standard video system was used to capture particle motion. Values of the drag coefficient of the rotating spherical particle were determined in a dependence on rotation particle Reynolds number.
