弯管差压测流最佳测量断面的选择

Selection of the Optimal Survey Section of Elbow Discharge Measurement of Difference Pressure

本文从分析弯管内水流运动规律出发，建立了弯管水流流量压差关系的基本公式。并通过大量试验，对弯管差压测流最佳测量断面的选择进行了较深入的研究，提出了最佳测量断面的选择范围，取得了规律性的有价值的结果。

Proceed from the analysis of water movement law in elbow pipe,the fundamental formuladischarge and pressure difference have been established.The depth study for selecting the optimal survey section of elbow discharge measurement by pressuse difference has been made through a lot oftests, the selection scope has been put forward,and the regUlarity and valuable resultS have been obtamed too.
