FIELD: machine building.
SUBSTANCE: stand has a supportive metal frame with a flow capacity installed on it, a pipe model considered with piezometers that is hermetically attached to the flow capacity, installed along the pipe and hydraulically connected to its lower part, and a receiving container. In addition, the stand is equipped with additional supporting metal frame and metal rails located between the supporting frames and connecting them. Reception capacity is installed on an extra frame, and a model of the pipe considered is hermetically connected to it. The model of the pipe considered is a corrugated road culvert made of transparent glass and placed on rails.
EFFECT: providing the possibility of observing the curve of the free surface, of water in the road corrugated culvert under unconfined flow regime, and the terms of charging of a pipe, and registration of increase of the length of discharge area with increased consumption.
