流量,是单位时间内通过某一断面的水的体积。流量常用单位是1m~3/s。在修建拦河闸、水库塘坝和沟渠时,必须精确计算河渠的流量。现介绍既实用又科学的测量方法,以供农村水利工作者参考。1 用水面浮标测定河水流量这种方法是用能在水面上漂浮的木板或干燥秫秸瓤等物,测出水面平均流量,再测出设置在水渠上的横断面过水面积, Flow, is the unit of time through a section of the volume of water. Common unit of flow rate is 1m ~ 3 / s. When building sluice gates, reservoirs, dams and ditches, the flow of the ditch must be accurately calculated. Now introduced both practical and scientific measurement methods for rural water conservancy workers reference. A water buoy determination of river flow This method is to be able to float on the water surface of the board or dried straw 瓤 and other objects, measured the average flow of water, and then set the cross-section of the water channel on the cross-sectional area,
