已知三通管来流流量，两出流支管的管径分别为和，若两支流管的断面平均流速相等，则两支管的流量分别为（）。https://image.zhihuishu.com/zhs/onlineexam/ueditor/201909/fed5bf8ee9db4252bcfa45623a443796.png
举一反三
- 如图示并联管路，已知各支路的沿程阻力系数之比为，管长之比为，且，则两支管的流量之比=（）。https://image.zhihuishu.com/zhs/onlineexam/ueditor/201909/6e209020d20f4543823ce6516ae8ca06.png

- 如图，两简单管道：a图为自由出流，b图为淹没出流，若两管道的作用水头H，管长l、管径d及沿程阻力系数λ均相同，则两管中通过的流量相同。https://image.zhihuishu.com/zhs/onlineexam/ueditor/201910/147dfa4c5286494ba558f9d5188337a6.png
- 某变径管的雷诺数之比，则其管径之比为（）。https://image.zhihuishu.com/zhs/onlineexam/ueditor/201909/4c46a5b24a004e54be6d53f4ab76db13.png
- 两根长度、直径、材质均相同的支管并联,两支管流量相等
