To derive the Bernoulli equation, we apply the work-energy theory to the fluid in a section of a flow tube. 我们应用功能原理来导出流体在一段流管流动的伯努利方程。
A analytical mode matching method is developed for the sound propagation through rectangular flow duct with mean flow and with lining. 流管实验装置是测量有流动情况下航空发动机消声短舱内声衬声阻抗的主要装置。
This paper examines the fluid dynamical characteristics of the duct flow in a swirlmeter by using the computational fluid dynamics approach. 本文运用计算流体动力学方法研究旋涡进动流量计的流道流体动态特性。
By controlling the piston stroke and the resistance on flow Passage,the fluid lift height and the pump speed can be controlled,thereby ideal lifting effect can be achieved. 通过控制活塞行程及泵内流道阻力，从而控制泵举升液柱的高度和泵的运行速度，取得理想的举升效果。
