FIELD: construction.

SUBSTANCE: bench comprises a base, a pipe installed on it, a source of a traction force, a block, a cord thrown over it, to the end of which a weight of alternating mass is suspended. At the same time the pipe is arranged as detachable with the possibility to model pipelines of different diameter, having branches with different angles and radii and transitions with different dimensions and narrowing shape. Inside the pipe at its end there is a mountainous sleeve fixed, the middle part of which is connected with the other end of the cord, and a source of a traction force is a vacuum pump or a vacuum cleaner connected to the pipe, to pull underpressure in it, with a hose via a transition and a tee with a vacuum metre.
