To derive the Bernoulli equation, we apply the work-energy theory to the fluid in a section of a flow tube. 我們應用功能原理來導出流體在一段流管流動的伯努利方程。
A analytical mode matching method is developed for the sound propagation through rectangular flow duct with mean flow and with lining. 流管實驗裝置是測量有流動情況下航空發動機消聲短艙內聲襯聲阻抗的主要裝置。
This paper examines the fluid dynamical characteristics of the duct flow in a swirlmeter by using the computational fluid dynamics approach. 本文運用計算流體動力學方法研究旋渦進動流量計的流道流體動態特性。
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. 通過控制活塞行程及泵內流道阻力，從而控制泵舉升液柱的高度和泵的運行速度，取得理想的舉升效果。
