Description
ют среднюю в сечении скорость с помощью малоинерционного прибора (например, гидр акустического) и глубину потока, а также скорость изменени глубины с помошью уровнемера, на выходе которого установле дифференцирующее устройство, В этом же гидростворе определ ют разность уклонов дна и свободной поверхности с помошью уклономера, выполненного в виде дифманоМетра . Измеренные величины подставл ют в указанное выше соотношение и определ ют искомую величину. Формулайзобретени The average velocity in section with the help of a low-inertia device (for example, acoustic hydro) and the depth of the flow, as well as the rate of change of depth using a level gauge, the output of which has a differentiating device installed. , made in the form of difmanometr. The measured values are substituted into the above ratio and the desired value is determined. Formula Investigation
