Preparation and Study on a Kind of New Testing Device for Fluid Resistance

1种新型流体阻力测试装置制作与研究

Fluid resistance small, the drag coefficient and the length of the tube with the same paragraph.

流体阻力小, 其阻力系数与同长度的管段相等.

Convenience sluice gate rapidly, energy, fluid resistance small, you can always operate.

启闭方便迅速 、 省力 、 流体阻力小, 可以经常操作.

On the basis of the weighted average flow velocity, approximate formula for calculation of fluid resistance ratio in eccentric and non-eccentric sprial channels was deduced.

依据此流速推导了偏心与未偏心螺旋通道中流体阻力之比的近似公式。
