STUDY OF WATER FLOW RATE IN THE GATES OF HYDROPOWER AND IRRIGATION FACILITIES

Abstract

The results of the calculated and experimental studies of water velocity distribution in the central vertical crosssection of flow in the plane of the shutter are introduced. Shutter model allowing to investigate the water rate for conventional planar gate and the gate to the guide flap is presented. It is shown that the relative coordinate section characterizing the average water flow rate is not independent on the height of the water level and the shutter opens, but only on their ratio. Experimental graphical dependence of the average velocity of the water in the central vertical section shutter and coordinates of its position are introduced. Experiments showed that the water flow in the gates has a vertical speed component.. The obtained results enable us to develop methods for measuring the water flow in the gate.
