Measurement of clean water flow in closed conduits . velocity - area method using current - meters in full conduits and under regular flow conditions 密封管道中清洁水流量的测定.在整体管道中规则流量条件下的流速计测量法
Every minute about 340 , 000 cubic meters , or close to 379 , 000 tons , of water pours in torrents over the cliffs of the falls of niagara 每分钟大约有34万立方米，或者说近37 . 9万吨的水流量从尼亚加拉瀑布的悬崖边湍急而下。
The working principle of water flow sensor is analyzed , and the comparison between water flow sensor and differential water - gas valve is made 摘要分析了水流量传感器的工作原理，将水流量传感器与压差式水气联动阀进行比较。
As for the latter relationship , by fitting in the two phases of time , the function expressions of the sand discharge capacity and tonnage is gained in the end 按时间分为两段进行拟合，最终确定了排沙量与水流量的函数关系。
