Abstract A method is proposed for calculating the motion of rafts floating on the surface of a river and for long capsules within delivery pipelines. The investigation gives a quantitative estimate of Prandtl's qualitative conclusions to the effect that floating streamlined bodies can travel faster than the flow of the river (for turbulent flow regime). The calculations showed, and an experiment confirmed that the motion of a raft or barge exceeds the flow velocity on the surface of a river by approximately 1.5 times. Similar conclusions are obtained for the motion of long capsules of neutral buoyancy in the case of turbulent flow of a liquid in a pipeline. In the case of a laminar flow regime of the liquid, effects of the opposite kind occur.
