流转率, 流转速度

Rated flow coefficient
额定流量系数
Test for 50 000cycles at a rate not exceeding 10 cycles per minute of alternating flow through the device of zero to the rated flow in accordance with table 12 . 2 , at ambient water temperature
在环境水温下，按照表12 . 2 ，以每分钟通过装置的交变流量（在0 ~额定流量之间）循环次数不超过10的速率，进行50000次循环测试。
The open angle , head loss and hydrodynamic pressure under the rated flow and several kinds of proportion are carefully observed in the model test , and these results are given for reference in engineering design
阶段模型试验中详细观测了在额定流量下，不同比重拍门的开启角度，水头损失及门体动水压力变化情况，以供工程设计应用参考。
Points out that some designers only use empirical methods in determining the inner diameter of pipeline , calculating system resistance and selecting the rated flow and rated head of circulating pumps in water systems
摘要指出目前一些设计人员在设计空调水系统时，仅根据经验值估算管道内径、计算管路阻力和选配系统循环水泵的流量和扬程。
