The water flow velocity in the suction pipe, which is crucial for evaluating the performance on pumping fish, can be measured by the pumped water flow rate of the riser in an air lift pump system.
气力提升泵的水输送量反映了提升管进口的流速情况，而进口流速是衡量吸鱼效果的重要因素。
After alkali treatment the hygroscopicity, suction lift and dye uptake of BTTPF were better than those of the pure polyester filament.
碱处理后的BTTPF，其吸湿率、吸水高度和上染率比纯涤纶更佳。
The higher the water temperature , the more likely it is to boil when exposed to a partial vacuum , thus reducing suction lift.
水温越高，在局部的真空下水更容易煮沸，因此减少了扬程。
Installations with suction lift require a good quality foot valve to avoid loss of prime - remove in-built check valve.
进水口的安装需要使用一个品质优良的底阀，以避免进水口压力损失-拆除内置式止回阀。
The surface suction opening is arranged on a floating body or a ship that is outside the floating rail, especially on a floating type air lift system.
表层水吸水口是安装在浮动围拦外的浮体或船上，尤其是构成浮动式气提系统。
Thus, in the worst case of zero leading-edge suction, the drag-due-to-lift factor K is simply the inverse of the slope of the life curve (in radians), as previously determined.
因此，零前缘吸力的最坏情况是：由升力引起的阻力系数K是前面确定的升力曲线斜率的倒数（弧度制）。
